- Tap a container to release a donut.
- Watch it travel along the moving conveyor.
- Donuts automatically enter eligible containers.
- Match four donuts of one color to complete and seal a container.
- Complete the required colors to finish the level.
New circuits. Fresh little challenges.
Circular and oval conveyors meet changing container arrangements. Every layout invites a different decision about which color to release next.


Easy to tap into. Room to think.
Simple taps. Four of a kind.
Tap to release, then bring four matching donuts together to seal a container.
