Follow the order of operations to solve each expression. Use BODMAS / PEMDAS rules. Solve brackets (parentheses) first, then powers and square roots. Next, solve multiplication and division from left to right. Finally, solve addition and subtraction from left to right. Choose the correct answer from four options. Select a mode: Easy, Normal, Hard, or Pro. Solve 15 questions to advance to the next level. Harder modes give more XP.
A typical puzzle session starts slow. You look at the board, work out what the rules actually are, and make a tentative first move. Then the pattern clicks and the next few stages go quickly, until one stops you cold. That rhythm, easy then stuck then easy again, is the whole appeal. Most sessions last ten to twenty minutes before you reach a natural stopping point.
Order of Operation Challenge rewards patience more than reflexes. Nothing punishes you for taking a minute to think, and the moment a hard stage finally gives way is worth the wait. It runs free in your browser with no download, so it is easy to pick up for a short break and leave again.
People who like to think rather than react, anyone killing time on a commute, and players who want something quiet to do with one hand on a phone. Younger children may need help with the trickier stages.
