Sega Swirl is a puzzle game that was created for the Dreamcast, Personal computer and Palm OS.
The most rewarding way to see the swirls disappear is when they all go into the air and burst with firework-like sounds and cheers.
The Dreamcast version featured a snake in the bottom right corner of the screen, who would act pleased when the player did well and shook his head when they did poorly.
If the player did nothing for an extended length of time, the snake would stare at them and then gesture to the left, towards the play field.
The Palm version of Sega Swirl includes a two player head-to-head mode that can be played in real-time over the handheld's infrared port.
