Three fresh puzzles every day. Six numbers, one target — how few moves do you need? No ads, no accounts, no internet required.
Every day, Operand gives you three number puzzles: Bronze, Silver, and Gold. Each hands you six numbers and a target. Combine the numbers with + − × ÷ until one of them hits the target exactly. Simple to learn, genuinely satisfying to crack.
Everyone in the world gets the same puzzles each day — solve all three for a Perfect Day, keep your streak alive, and share your results without spoiling the solution.
