Thumbnail0h n0 is a logic game, which has only three simple rules: blue circles can see other circles in the row and column where they are, the numbers in the circles tell us how many other circles are around, and red circles block their view. All you have to do is click on a circle and make it blue or red. You can play in Zen mode, or time trials.
