Math Box Balance
Boxes that have to balance, starting with two and growing.

Math Box Balance is a puzzle game with numbers. Early levels have 2 boxes, and as you progress you can reach up to 8 boxes. Each box contains 4 number blocks, and the sum of these numbers is shown inside the box. Your goal is to make the sum of all boxes equal. You can swap number blocks between boxes to achieve the equal sum. It is an endless game where the difficulty increases over time, your score goes up, and the fun grows with it.
Controls
Drag or tap to assign numbers to boxes.
How to Play
- Read what each box currently holds.
- Find the relationship you can resolve outright.
- Use it to constrain the others.
- Balance every box to finish the level.
Tips & Tricks
Solve the box with the fewest unknowns first. Everything else usually follows from it, and starting elsewhere means guessing.
Frequently Asked Questions
How many boxes are there?
Two at the start, growing as the levels progress — which is what turns a single relationship into several at once.
Is this algebra?
In substance yes, without the notation. You are resolving unknowns against constraints, just presented as boxes rather than letters.
