Basic terms accepted in this edition of the rules:
“Single” – a bet on a single event;
“Multiple” – this is a bet on the outcome of several different events simultaneously. When you place a bet on the outcome of two or more events (for example, two different football matches), you can unite them in an “Express” bet. To win an express bet it is necessary for you to not have any failed predictions (losses) on any of the outcomes which are included in the Express bet. Loss on one of the outcomes of an express bet means loss of the entire bet. Winnings of the express bets are equal to the product of the bet amount at the coefficients of played outcomes included in the Express (if on one of the bets included in the express a return occurs, then the coefficient on it equals 1).
“System” – a set of “express bets” on a particular set of events. Each combination of the system is calculated as a separate express bet. To win in the system it is sufficient that the indicated number of predictions of the total number be correct (it is defined by name, for example, in the system “3 of 4″ it is necessary that 3 of the 4 predictions prove correct, for “5 of 7″ it is necessary properly to predict the outcome of the five events of 7 options, etc.). It must be taken into account that because of the fact that only part of the total bet amount is specified on each of the express bets of the system bet (proportional to the number of options) then the winnings with such a system bet will be less than the possible general winnings with the express bet. In some cases, when not all outcomes are predicted, the amount of winnings may be less than the amount of the bet, but in contrast to express bets, a part of the amount will be offset on account of correctly predicted outcomes.
“Chain” – bet which is a combination of “single” bets including events independent from each other. The sum of single bet of each chain’s event is equal to the sum of the chain. The client is given a chance to determine independently the order of the bets included in the chain and stake only on the first event of the chain. Thus the concept of “chain account” is imported. After the tournament of each single bet included in the chain the sum of that account is calculated. Initially it is equal to the sum of the first bet.
