Ricochet Robots is a brain burning, group speed, puzzle boardgame. It can accommodate any number of players: as long as one can see the board, one can play. The board is set up up randomly, one of four colored robots becomes active, and a goal token is randomly selected. The goal is to get the active robot to the right token by ricocheting off walls and other robots that you move strategically in the path of the active robot. When you find the optimal path -- the route that uses the least number of moves for the active robot to reach the goal token -- you yell out that number. Then a one-minute sand timer is flipped and all other players are pressured to beat your solution with a lower number of moves. The tension and difficulty lies in the fact that since you can only use the board to show a solution and not while searching an optimal route, you must quickly navigate the active robot in your head, and get the lowest-number-of-moves solution before someone else yells it out -- a most difficult brain burning exercise. Every gamer should get a copy of Ricochet Robots because not only is it fun but it is the only game out there that can accommodate a mob of gamers.
Kevin Cowtan developed a Flash fanware of Ricochet Robots and has shared the code on several websites such as ricochetrobots.com.
PS: In the screenshot above, how many moves for the active, red robot (bottom left) to reach the red plus sign (top left)? Don't play with programmers...they excel at this game.
