The first and most important feature of a betting contract is that it is based on an uncertain future event. It may be a past event that has already taken place, but the parties are not aware of it. If a game requires skill or if skill plays a vital role in the results and the prizes are subsequently awarded, then the competition is not a lottery, but otherwise it is. A literary competition that requires skill is therefore not considered a betting contract.  But competitions where the winner is set at a chance, then it`s a lottery and it`s considered a bet.  Figure: A tram company driver agreed to be bound by the company`s general manager with respect to a current month`s count and salary in the event of a breach of the rules. The agreement was found to be valid. This is mentioned in Article 25(2) of the Law. Then, the promiser leads the plot in order to compensate all or part of the promise for a voluntary act of promise made previously. For example, if there is a contract between A and B that covers A`s expenses to care for her son, it should be noted that the service provided was not voluntary, as B is legally obliged to support her grandson. According to this exception, the promise must be to compensate a person who has done something for the promisor himself and not for a person who has done nothing for the promisor . The court decided that the agreement was void and stated that the restriction mentioned in the section does not always mean absolute deference, but also implies a partial limitation limited to a single location. This section focuses on the “frustration” of the treaty. It provides that the disappearance of the object makes it impossible to perform the contracts.
 In Krell vs. Henry, the respondent rented a room from the Claimant for two days, as possession of the king`s coronation would pass along that road. And in this sense, a certain part of the rent was paid in advance. But the goods were lifted when the king fell ill. Thus, the defendant refused to pay the full amount of the contract. A agrees with B to discover treasures through magic. The agreement is not concluded. The only reservation in this regard is that the agreement should be appropriate depending on the nature of the transaction. The purpose of this exception is to protect the interests of a purchaser of business goods or firms. . . .
