Finger Twister is a flash screamer game, that pretends to be a normal magic game, the game is now closed, and there are no archives of it, using Wayback Machine.
The game immediately requests the player to place one of their left fingers on the blue "L" circle and one of their right fingers on the red "R" circle. The challenge is to hold them onto the screen for more than 30 seconds nonstop, while the circles move around. After "BEGIN" is clicked, the circles start moving, but 8 seconds into level 1, a picture of a great white shark with its mouth open appears in the background accompanied by a sudden whooshing sound. The game is inaccessible including through the web archive.
