Before placing a bet, each player is obliged to read and acknowledge not only the General Terms and Conditions, but also these sportsbetting rules, including the provisions regarding minimum stakes, maximum payouts as well as maximum stakes.

Interwetten will accept a bet duly placed by the player by mouse-click, subject to these rules and the General Terms and Conditions, without issuing a confirmation and at the registered address of the company, provided that his Interwetten account holds sufficient credit. Any correspondence issued by Interwetten at a later point in time, (e.g. notices, account information, etc.) will not have any effect whatsoever on the previous conclusion of the contract and its legal effect at the registered address of Interwetten.

If changes are made to the odds while a bet is being placed (usually 5 to 10 seconds), the bet will automatically be accepted at the odds chosen by the customer. If the odds are lowered, the bet will not be accepted. The user will then be given the chance to update the betting slip and confirm it once again.

Any bet accepted in such manner may not be changed or cancelled by the player at a later point in time. Interwetten, however, reserves the right to cancel any bets up to the start of the event, without giving any reasons. After the event has started, Interwetten may cancel bets provided that the player is in violation of these rules or the general terms and conditions as applicable from time to time, or, in particular, if he is under the suspicion of manipulation/rigging, of acting in collusion or forming a syndicate of customers, keeping duplicate gaming accounts or using front men in order to place bets.

Only the records kept by Interwetten shall be relevant concerning the content of all bets. A statement of account may only be modified in order to remedy an obvious error and/or a typographical error and/or an error in calculation. Only the amount registered and/or the amount confirmed by Interwetten will be regarded as the stake.

Interwetten's promotions, special offers and bonuses are only valid for the respective period specified. Where promotions, special offers and bonuses are specifically addressed to an individual or to specific sportsbook account, offers are only valid with respect to these individuals or accounts so specified.

The decision as to honour any special promotion, offer or bonus shall be entirely up to Interwetten. Interwetten also reserves the sole discretionary right to discontinue or cancel any promotion, special offer or bonus at any time and for any reason whatsoever, without prior notice.

All rules and principles of the Interwetten Sportsbook apply equally to the Cash-Out function. Interwetten cannot guarantee that the Cash-Out feature is available at all times. Due to, for example, technical issues, human error, suspicions of fraud or other circumstances beyond Interwetten's control, Cash-Out might not be offered for a particular event or betting market, even if the feature had been advertised before-hand. Interwetten reserves the right to withdraw or suspend Cash-Out offers without prior notice.

Unless Cash-Out is available and exercised by Interwetten upon request, the player's bet stands as originally placed.

If bets have been cashed out with incorrect amounts due to technical reasons, an error in the underlying odds, or for any other reason, Interwetten reserves the right to suspend the Cash-Out option and reverse any transactions made. In these cases, the player's bet stands as originally placed. The same rule applies if there is sufficient reason to suspect that the Cash-Out is requested after the outcome of an event is known by the player.

If a sports event is not held as posted on the internet (e.g. if the venue or the opponent changes), the bet will be void and all stakes will be refunded. However, bets will not be void if the home team waives its right to play in its own stadium or arena and chooses to play a match on another team's ground, if the home team's arena/stadium is temporarily closed or if the match is held at a neutral site. This does not apply to friendly matches or test matches as these often take place as part of a training camp, promotion tour, or because of logistical reasons at neutral venues. Furthermore, this does not apply to so-called bubble events that are held at central locations due to external circumstances.

If bets are placed after the start of an event or if the stake is not paid before the start of an event, the bet will be void, rated at odds of 1.00 and the stake will be refunded. In live (running) bets, each bet placed (= received) after the event on which the bet was placed occurs, will be void, rated at odds of 1.00 and the stake will be refunded.

The winner of a sports event is determined by decision of the jury at 24:00 midnight on the day of the event (local time at the venue of the event). This also applies to long-term bets. Any change in the results arising after that time for any reasons whatsoever will have no effect on the winnings.

In soccer (European football), ice hockey and handball the results after the scheduled duration of the game are relevant. Any extra-time, penalty shootout, etc. will have no impact on the winnings, with the exception of special bets offered, which are marked accordingly.

If a betting event is canceled, special bets that were already decided when the game was stopped, or half-time bets, are evaluated according to the course of the game.

In American football, basketball and baseball overtime counts for settlement purposes. An exception from this rule may apply for special bets that are clearly marked accordingly.

If there is no winner due to the "point spreads" (e.g. a team with -6 points has exactly a 6 points lead to win), then the bet will be valued at odds of 1.00. The stake is refunded.

If a game that has been declared void is repeated by the end of the second day following the game (local time of the venue), the wager will stand for the re-arranged match.

If a game is not played at the scheduled date for any reason whatsoever or ends without official score and is not repeated by the end of the second calendar day following the game, the stakes will be returned, with the exception of soccer and ice hockey games that are stopped after the end of the regular time.

In tennis, bets will stand provided that the match is played in the course of the tournament.

If the result of a match in tennis, volleyball, beach volleyball, darts, badminton, snooker, bowls or table tennis is based on a no-show, retirement / surrender or disqualification of a player, or if the match is not continued until the regular end of its playing time for any other reasons, stakes will be refunded. In combination and system bets these stakes will be evaluated with an odd of 1.0.

Exceptions from this rule are events that have been concluded within the available time frame (e.g. if a player surrenders during the second set, bets on the first set stand). In addition, bets are rated as lost if they could not have been won, even if the match was continued up to regular playing time (e.g. set bet "player A wins 2-0" and player A surrenders during the second set after having lost the first set. All other options, i.e 2-1, 0-2, 1-2 will be rated as cancelled and evaluated with an odd of 1.0).

On the other hand, bets are rated as won if they could not have been lost, even if the match was continued up to regular playing time (e.g. the bet "over 9.5 games in a set" is won if the game is decided by surrender at a score of 4:4).

The same principle applies also to game handicap bets, scores set/points and comparable bets.

If a tennis match is cancelled even before the first serve is made, all bets will be void, rated at odds of 1.00 and the stake will be refunded.

A baseball game is cancelled, and the stakes refunded if the game is not begun or continued until the end of the day (local time of betting event) of the original scheduling.

If a sporting event is canceled and still officially scored, this result will be used to calculate the winnings, provided this is announced by midnight on the day of the event measured at the location of the event.

If a game is abandoned before the end of regular time, bets on North American sports (NBA, NFL, NHL, baseball as well as college sports) will be official after the following limits: NBA - at least 43 minutes of play WNBA; college basketball - at least 35 minutes of play NFL; college football - at least 55 minutes of play; Baseball - after at least 5 innings of play and/or 4.5 innings if the home team is leading.

When wagering on baseball total runs or run-lines, the games must go nine (9) innings or 8.5 innings, if the home team is leading in order to have action; otherwise the game is scored as no action.

The final score will always be determined as the score after the last completed inning unless the home team scores to tie or take the lead in the bottom half of the inning, in which case the final score is determined as the score at the time the game is called.

For a so-called "dead heat", winnings will be divided accordingly. If, for instance, two starters in a race end up on the same podium position (winner) based on identical timings, then the selected odd on "winner" is being divided by 2: 2.5/2 = 1.25.　 Bets on podium finish 1-3 will be divided accordingly if 2 or more participants share the third place. If 5 starters share position 8, the winning for a bet on "top 10 finish" will be calculated with 3/5 of the original odd. If, on other hand, 2 starters share position 2, the original odd for a bet on "podium finish" will remain in place as the third position remains vacant.

All bets, also combination bets, which are not head-to-head bets, are "play or pay". In other words: no refund will be given, if the competitor on whom the player has placed his bet does not participate in the event for any reason whatsoever.

If one of the selected events in a combination bet is cancelled, abandoned or becomes void, or is not held for other reasons and is not run by the end of the second calendar day following the event, the bet will be void, rated at odds of 1.00 and the stake will be refunded. This also applies to sports events that have been mistakenly listed in the wrong order on the betting program (list of odds), but not in the case of a home team waiving its right to play in its own stadium or arena, if the home team's arena/stadium is temporarily closed or if the match is held at a neutral site. If all the single bets in a combination bet are cancelled, abandoned or declared void, or are not held for other reasons and are not run as specified above, the stakes will be returned.

For head-to-head bets both starters have to participate in the sports event. Should one or both starters not participate in the event, the bet will be void. The winner of a head-to-head bet on Formula 1 Grand Prix races is the driver with the higher finishing position at the end of the race, or the one who completes the most number of laps in case that both drivers fail to finish the race. In the event that the two drivers retire on the same lap, the driver with the better placing after completion of the last lap will be the winner.

Bets on betting markets in which not all possible outcomes are listed are generally considered lost if the guessed outcome does not apply.

Individual types of bets and special bets are ruled by separate terms and conditions indicated in the individual offer.

For Betbuilder bets, all tips within the selected event must be correct for the bet to win. If one or more tips are invalid (e.g.: match abandoned and not continued within 48 hours) or if a selected player does not take part in the match, the entire bet will be declared invalid and the stakes refunded. The stake will not be refunded if 1 selection tip has already been lost in the event of the match being abandoned. Penalties that are not directly converted are deemed to have been missed, even if the follow-up shot leads to a goal. Furthermore, bets on “milestones” (who reaches X points first) are also lost if neither team reaches this target.

The bets are paid out taking into account the maximum amounts determined by Interwetten.

The minimum stake for a single bet and combination bet is: EUR 0.50

The minimum stake for each column in a system bet is: EUR 0.30

For all other currencies that may be in use form time to time the minimum stake is indicated on the player's betting slip.

Maximum Winnings

The maximum winning per player in any one week (Monday 0:00 to Sunday 24:00) is the following net amount: EUR 100,000.

4.1 Win and Loss Probabilities

The probability of winning a sports bet depends on the probability that the forecast for the betting sports events occurs. However, the probability of a certain outcome of a sporting event cannot be determined mathematically exactly in advance.
Sports experts, fans and bookmakers naturally come to different assessments here. With the odds, bookmakers express an assessment of the possible gain or loss.
In order to be able to understand an assessment, you have to divide the reciprocal value of the odds of the selected game outcome by the sum of the reciprocal values of the odds of all possible outcomes of the betting event:

Probability Bet1 (in %) = 1/Odd1 divided through 1/Odd1 + 1/OddX + 1/Odd2

4.2 Betting odds

There are no additional costs associated with participating in a sports bet apart from the stake. In the event of a win, however, the payout amount is reduced by a 5,3% odd discount.

You can find out whether you have won by looking at sports coverage in the media and, if possible, by looking at the results displayed on the sports betting providers' homepage.

A general publication of individual prizes does not take place. Interwetten.de reserves the right to anonymously inform about large prizes in individual cases.

The percentage of payouts for winnings from the stake (payout rate) is usually in a range of 90-95% at Interwetten.de.

In the case of combination bets, the payout rate is reduced, based on that for single bets (q), according to the number of outcomes in the combination bet. (Payout bet, two-way combination: q², three-way combination q³, etc).

Example: Single bet q=9/10=90%

Two-way combination: (9/10)² = 81/100 = 81%

Three-way combination: (9/10)³ = 729/1000 = 72,9% etc.

The average payout ratio of interwetten.de is subject to fluctuations.

Payout ratio Three-Way (in %) = 1 divided through 1/Odd1 + 1/OddX + 1/Odd2
