Cromo is a simple strategy game for 1-2 player. Which can be played either against each other or against the computer. The goal is to achieve the highest possible score by "clearing" colored stones. The value of the green stones is credited to the points account and the value of the red stones is deducted. It is therefore quite possible for the "score" to slip below zero (a red dot next to the number display indicates this) Taking takes takes place vertically or horizontally. The last stone taken determines the row from which the next stone must be taken. The game ends when all stones are removed from the playing field or a player can no longer "take". Whoever has the highest score wins the round. A game lasts 5 rounds.
