color deducto

a game designed by Jon Orwant and Walter Bender
1. Insert quarter.
2. Try to discover the rule that defines the pattern.

The "example" button generates an example of a pattern that obeys the rule of the current level. The "counter" button generates a counter example. The "play" button begins play. You need to correctly evaluate five examples in succession to advance to the next level.
