Math Box Balance is a free online math puzzle game where your goal is to swap number blocks between boxes until every box shows the same total sum. Starting with just 2 boxes, each holding 4 number blocks, you can see the current sum displayed inside each box, making it easy to spot which numbers need to move and where they should go.

As you progress, the game scales up to 8 boxes simultaneously, which means you are juggling a lot more numbers and swaps to find that perfect balance. Each level cranks up the difficulty gradually, so you are always pushed just enough to stay engaged without hitting a frustrating wall. Your score keeps climbing the further you get, giving you a real reason to keep playing and beat your personal best. The endless format means there is always one more round to try.

Math Box Balance is perfect for kids practicing addition and mental math, students who want to sharpen their number skills, and adults who enjoy logic puzzles and brain training games. Whether you are looking for a free math game for kids, an educational puzzle game for school practice, or just a quick number balancing brain teaser to play in your browser, this game delivers a satisfying mental workout every time you play.
