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. Horizontal, vertical, and non-neighboring Normal-mode connections display guidance without a penalty. However, a diagonal connection that fails the arithmetic check costs 10 seconds, and three arithmetic mistakes end the game.

Earn in-game IQ Points based on the selected mode, board size, 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 complete a rewarded ad. Hints require an internet connection, and closing the ad early does not consume a hint. Used hints are stored with the local result and considered in leaderboard rankings.
