Create and share the board
Create a challenge before a round, from the pause screen or after finishing. CornerWISE packages the board and its settings into a QR code that can be shared as an image.
Friends can scan the code with their camera or import the image from their device. No online account, username or central friend list is required.
One official attempt, with safe continuation
Starting the challenge uses that installation's official attempt. If the game is interrupted, its continuously saved progress can be continued later instead of consuming another attempt.
Finished or deliberately deleted attempts cannot be replayed, keeping the comparison meaningful while still protecting players from interruptions.
Build a combined local ranking
After playing, each participant can share a signed result QR image. Import the results on one device to build a combined challenge ranking.
Results are ordered by completion percentage, fewer hints, shorter time and higher score, so everyone can compare more than a single point total.
