The game is played on a 4x4 field.
The player's task is to collect rings of the same color in a row.
A row of rings of the same color disappears.
For each missing ring, the player receives 30 points.
Rings come in three sizes.
Rings of the third size (dots) appear after receiving 400 points.
If three rings of the same color are collected in one cell, all rings of this color on the field disappear.
The player can change the rings three times.
The player can change the rings for watching an advertisement.
If the entire field is filled in, the game is over.
When the game is over and this is the player's best score, the player gets into the high score table.
