Speedo is a three-player group size game similar to Spao, involving both removal and placement each turn for a deeper game. Start: The board starts empty. White places a white ball on any hole. Play: Players take turns: removing a movable ball of any colour, and placing two balls (one of each colour not removed) at any two playable points. End: The game ends when the pyramid is completed. Each player counts the sizes of their visibly connected groups and multiplies their counts together. Highest score wins. Like Spao, each game will last exactly 30 moves. Unlike Spao, hidden connections do not count, and the combined removal and double placement leads to more complex and dynamic board positions.
