Twenty equations in five rounds, easy to hard, each with one number taken out, like 7 × ? = 56. 20 seconds each, one life. Pick the number that makes the line true; every problem you clear is a point. Keys 1 to 4 answer. The clock starts when you do.
About Gap
Gap is a free daily mental math game from Mind Loft, and the backwards sibling of Blitz. Every one of its twenty problems is an equation with one number taken out, like 7 × ? = 56, and you pick the number that makes it true. The lines climb through five rounds, from one-step sums and the times tables up to two-step lines, brackets, percentages, squares, cubes and roots. You get twenty seconds each and one life, so your score is simply how far up the ladder you got before a wrong answer or an empty clock stopped you.
The four options are not padding. Every wrong answer is a mistake somebody actually makes when they run an equation backwards: adding where they should subtract, dividing the wrong way round, forgetting the tail on a two-step line, answering with the result instead of the gap, the times-table entry next door. You cannot pick the right one out by its last digit or by its size, so the only way through is the arithmetic, and the surest check is to put your pick back into the line.
Everyone plays the same twenty problems in the same order each day, so the daily leaderboard is a straight fight: furthest wins, and ties break by time. Twenty new problems drop every day at midnight Eastern. No app, no signup, play free in your browser, keep a streak, and race the daily leaderboard. It is one fifth of the Math Gauntlet, with Blitz, Blitzed, Series and Back.
