CornerWISE

About this game

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 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.

Challenge your friends to play the exact same board with the same settings. Create a challenge before starting, from the pause screen, or after finishing a round, then share it as a QR code. Friends can scan the code with their camera or import the QR image from their device. Each player gets one official attempt, while interrupted challenges can be continued later.

After playing, share and import results to build a combined challenge ranking. Results are ordered by completion percentage, hints used, seconds per point, and score—just like the regular leaderboards.

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 watch 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 and challenge rankings.
