Years ago I played a game similar to Ricochet Robots, but a single player travel version.
This game has a small board (something like 5x5 tiles) and several robot pieces. It includes cards with puzzle configurations (about 100 I remember) that the player should solve.
The mechanics of the game are similar to Ricochet Robots (or a Zelda ice and blocks puzzle), where you move a Robot in one direction until it collides with another element. The objective is to get the robot to a selected position on the board.
I don't remember the name nor the company that made this game but I want to try it again. Does anyone know it?
