Without Fail is a party game of seemingly easy challenges that are made horribly difficult by the other players.
The game includes 150 challenges that involve props like a blindfold, cups and balls, dice, pens, and more – all provided in the game box. The challenges are simple, but there's a catch: Before a player begins a challenge, their friends bet on how difficult the challenge can be made without failing. The friend who makes the challenge the hardest becomes that player's teammate, and they both score if the player can successfully complete the challenge. However, if they upped the stakes too high and the challenger fails, then all other players earn a point, and the challenger and their teammate both lose points. Success is based entirely on whether players are good judges of their friends' abilities.
