CubePlusMinus

Add or subtract, merge and climb. Plan each move, break your high score.

CubePlusMinus is a minimalist strategy puzzler. Place given plus or minus tiles onto numbered cubes to increase or decrease their values. Whenever three or more adjacent cubes share the same number, they automatically fuse into a higher-value cube and award points. Every placement matters—use clever sequencing to trigger massive chains and keep pushing your score higher.
Arithmetic Fusion: +/- tiles instantly alter values and spark chain reactions
Triple Merge: matching cubes auto-upgrade to the next tier
Tactical Placement: Each move determines the length of future combos
Escalating Challenge: As more and more digital blocks appear on the board, the difficulty increases.
Pure Brain Power: No timers or power-ups—pure strategy on demand.
