Brain Calculator is a browser puzzle game that challenges your number sense and logic. Each level gives you a starting number and a target number. Use a small set of operations to change values and reach the goal. Operations include add, subtract, convert digits, reverse digit order and special "stuff" moves that insert or remove digits. Levels vary by available moves, digit limits and time or move caps.
Gameplay focuses on planning and precision. You pick a number tile, apply an operation and watch the result. Some levels allow chaining of operations, while others limit moves to increase difficulty. The game rewards efficient solutions with higher scores and unlocks progressively harder puzzles. Brain Calculator trains mental arithmetic, teaches patterns in numbers and appeals to players who enjoy logic, speed and optimization.
