Urjo is a series of logic puzzles. Each circle in a grid of either 4x4, 6x6 or 8x8 circles will 1. have every row and column contain an equal number of red and blue circles, 2. every numbered circle will have as many of that space’s same-colored circles adjacent to it (including diagonals), and 3. there will be no two adjacent rows or columns with the same pattern of red and blue. Each puzzle has a unique solution, and there seems to always be a way to figure out each one without mistakes. Play the tutorial to get used to the rules, then plunge into solving puzzles. You can create an account to place on leaderboards for each puzzle.
