How far can you gently fold before deciding to stop? EdgeDare makes the held angle and your timing the challenge.
Keep a narrow opening to build your score, then reopen to bank it. Closing too far ends the round with no score. Try the steady, sway and feint stages, compare with your previous attempt, or take turns with a friend. Share a result card when you want to.
This is not a closing-speed contest. Move gently and take a break when your hands tire.
Every stage also works on a non-folding iPhone with an on-screen slider. The free version has ads; a one-time purchase removes them and unlocks all three stages.
