Colliso Puzzles

To move a tile, first select the tile by clicking on it and hold down the mouse button. Then move the mouse in the direction you want the tile to move. Once you release the mouse button, the tile will slide towards the direction you have specified (the arrow shown indicates the direction). If the tile collides directly with another like tile at the end of the move, both tiles will be removed. Note that a collision must occur, which means that just having two like tiles side-by-side will not remove them. If two different tiles collide, they will swap colors. Obviously, this will not have any effect if the tiles are of the same color. In later levels, the tiles can be of black, white or red colors. To solve a level, you must remove all the tiles from the board. If you solve a puzzle within an indicated number of moves, you will unlock a bonus + level. In this bonus level, you will solve the same puzzle four times consecutively. However, the level will be somewhat different each time - the level can be flipped horizontally, vertically or both ways. Just when you think you have solved a level, having the level flipped will disorient and twist your mind!
