Game

Applies at once, also to the running game.

Level progression (game screen)

Level 1 starts with the smallest grid. Every few levels the grid grows by one cell. All other generator values rise with the grid size. Every player gets the same level N.

Level (lab screen)

Applies to the next generated level in the lab screen.

Flight path: how many cube edges an arrow crosses before it leaves the cube. More edges block many more arrows: at 20×20, +1 edge leaves about 1 % of the arrows open at the start (own face: about 10 %). +2 and +3 give sparser levels and take 1–3 s to generate.

Difficulty is the number of candidate arrows the generator compares for each placement. It keeps the one that is hardest to free: both ends far from the face edge. Large grids with long arrows give the deepest levels.

Tester and designer

Players see only the appearance settings. Tester changes always stay on this device, and the tester progress never reaches the server. Designer changes stay on this device until you publish them. "Publish to server" sends them to the server; every player gets them at the next start. Without a server, copy the config and save it as config.json next to index.html. Active base config: . App version: .
