CornerWISE

CornerWISE is a fast-paced number puzzle where simple arithmetic becomes a clever visual challenge. Each board is filled with random numbers. Connect two diagonal corners when addition, subtraction, multiplication, or exact division of the connected numbers produces a value in either of the remaining corners. Every matching operation scores a point, so a single line can be worth several points. Play Normal mode with neighboring corners, or switch to Expert mode and search across rectangles of any size. Complete timed boards before time runs out—or choose Endless mode—but choose carefully: an arithmetically invalid diagonal adds a 10-second penalty, and three mistakes end the game. Other invalid gestures display guidance without a penalty. Earn in-game IQ Points based on the board’s difficulty, number range, time setting, and your completion percentage. Progress through karate-inspired belt ranks from white belt to black belt, 10th dan, and unlock increasingly challenging Expert board sizes along the way. If you get stuck, a limited number of optional hints can reveal one missing line after you choose to watch a rewarded ad. Your use of hints is recorded and considered in leaderboard rankings. - Normal and Expert game modes - Random boards from 3 × 3 to 7 × 7, with adjustable number ranges from 1–6 to 1–20 - Timed, Endless, and 10s+ time-extension modes - Interactive tutorial explaining valid lines, scoring, and penalties - Limited optional hints for revealing missed connections - Difficulty-based IQ Points and karate-inspired belt progression - Expert boards unlocked through belt advancement - Live seconds-per-point pace during every game - Multiple color themes and patterned backgrounds - Separate local leaderboards for every game setup - Rankings based on completion, fewer hints used, seconds per point, and score - Protected export and import for local progress and results - Available in 14 languages No account is required.
