## What is 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

No account is required. Your game data remains on your device unless you choose to export a backup.

Every board creates a new challenge. Improve your completion percentage, sharpen your pace, advance through the ranks, and find the wisest route from corner to corner.
