About game
Math challenges move at a frantic pace when you have only three seconds to make the right choice. Rounding turns simple arithmetic into a high-stakes brain puzzle that tests your agility under pressure. You watch numbers drop from the top and must tap a column to add them before the timer runs out. Achieving a sum that ends in zero clears the column and boosts your score significantly. Strings of perfect additions trigger a multiplier effect that sends your score skyrocketing toward the top of the leaderboard. Managing your column values carefully prevents them from crossing the one-hundred threshold and locking up your board. Earning stars keeps your game alive when things get tough while letting you customize your profile with new frames or fonts. Play Rounding right now in your browser without any downloads or registration.
How to play
- Within 3 seconds, select a column whose value will be added to the number that falls from above.
- Make the sums round (multiples of 10) to earn points, and the column will be reduced by 10 (the 0 will be discarded).
- Multiple rounds in a row activate the ×2 mode and double the points.
- A column with a value of exactly 100 earns a star ★.
- If the value becomes non-round and exceeds 100, the column will be locked. It can be unlocked for one star.
- You will lose when all the columns are locked.
Control: click or tap on a column.
