Finger Twister is a flash screamer game, that pretends to be a normal magic game, the webpage is now closed, but can be accessed using Wayback Machine.
The game asks the player to put one of their left fingers on the blue "L" circle and one of their right fingers on the red "R" circle right away. The task is to keep them on the screen for more than 30 seconds as the circles move around. The circles begin to move after they press "BEGIN."
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.
