About Math Chain
Math Chain is a quick mental-arithmetic challenge. Solve each sum by choosing the correct answer from four options. Early levels use addition and subtraction, later ones add multiplication and division with larger numbers. You have three lives, so accuracy counts.
How to play
- Read the equation and tap the correct answer.
- Each wrong answer costs one of your three lives.
- Answer enough questions correctly to complete the level.
Tips and strategy
- Round numbers to the nearest ten to estimate, then adjust.
- Eliminate options that are clearly too large or too small.
- For multiplication, split one number into tens and ones.
Levels, stars and XP
Finish a level to earn one to three stars and XP towards your player level. Replay any unlocked level to improve your stars. From level 151 the game enters endless mode, where each level is a remix of an earlier one with fresh colours and a slightly higher difficulty.
