How to play Junretsu? It is simple! There are three types of boards, 3x3, 4x4 and 5x5. Each cell in the board contains a colored game piece. Each piece contains 4 colored small pieces, located top, right, bottom and left of the piece. Rules of Junretsu are simple. In each level, you can slide pieces to left, right, up or bottom to rearrange them. You can also rotate them in a Difficult mode. Aim of Junretsu is to rearrange the game pieces so that main colors of neighbors of a piece are the same as the corresponding inner colors of the piece. For example, inner-right and inner-bottom colors of the top-left piece must be the same as the right and bottom neighbors of it. Similar equalities must hold for all game pieces. In the EASY mode, there are many solutions to each game, so it is easier to find a solution. In the MEDIUM mode, there are either a unique solution, or only a few of them. In the DIFFICULT or VERY DIFFICULT mode, the game pieces can be rotated clock-wise. In the initial game, the inner colors are also permuted, so you need to determine the place and the orientation of all pieces. Also there are many solutions to any puzzle.
