Once an event is completed. The Wagerr network recognises the outcome and the betting contracts are paid out. This usually occurs within ten minutes of the event finishing.
However, when a payout occurs it remain immature for 60 minutes (60 Blocks). This means that you will not be able to place another bet with the winning funds until after this period. It is likely that this gap will be reduced with updates to the Wagerr blockchain.
Occasionally events need to be voided and bets refunded for a number of reasons. In this case the chain will refund every bet by minting WGR equivalent to the bet amounts.
