MAKE MENTAL MATH FEEL LIKE A GAME Game Zero turns addition and subtraction into a fast, original strategy puzzle. Instead of working through another worksheet, you read the board, choose a number, and try to bring five targets to exactly zero before time runs out. A SMART DAILY BRAIN WORKOUT Every move asks you to calculate, plan, and adapt. Play regularly to practice: • Mental addition and subtraction • Number sense and arithmetic fluency • Focus and quick decision-making • Logic, pattern recognition, and multi-step planning Game Zero is enjoyable extra math practice for school students who want to become quicker and more confident with numbers. It is equally satisfying for adults who enjoy brain training, number games, and short strategic challenges. SIMPLE RULE. REAL DEPTH. Tap a tile to add its value to all open targets. After every move, play switches between a row and a column, and the signs flip. A completed zero stays locked only temporarily, while used tiles need time to recover. You are always balancing calculation, timing, and the next move.
