/**
 * @title OneOnTen
 *
 *
 * Decentralized gaming room contract that allows players to join rooms and compete.
 * 
 *
 * Two modes available : 
 * - 1v1 gives you 50% probability of winning ( you win 80% of the total pledge of all players ). This mode finishes as soon as the second player enter the room.
 * - 1v10 gives you 10% probability of winning ( you win 80% of the total pledge of all players ). This mode finishes as soon as the 10th player enters the room, or after around 1200 mined blocks - around 4h ( you are refunded after the timer ends if no other player's joined ).
 *
 *
 * In order to access a gaming room you just need to enter the desired ETH amount you want to play and select the game mode.
