Limbo
Pick a target multiplier. If the result beats it, you win target x bet.
How to play
Set a target multiplier between 1.01x and 1000x and place your bet. The game then draws a result multiplier. If the result is at or above your target you win your target times your bet; if it is below, you lose the stake. The higher the target, the rarer the win and the bigger the payout.
