Light PathThree glowing 5×5 logic modes with 253 levels: trace every cell, connect colored endpoints, or join white lights. Includes daily puzzles, friend challenges, guides and sound.
Keyboard: arrows to choose a cell, Enter/Space to start or finish, Escape to cancel the current path.
Use the level input or Previous/Next to choose a puzzle. Daily challenges refresh by UTC date, with one shared puzzle per mode each day. Invite Challenge opens the site share dialog with the exact board, without a login. Sharing after a win includes your time. Times are self-reported by the browser, not verified rankings. Use Sound to toggle game audio.
Find the green start. Plan how to visit edges and corners without isolating empty cells. Move one cell at a time horizontally or vertically, never diagonally.
Hold the start and trace every light without releasing. Visiting all 25 cells wins immediately. Keyboard players press Enter to start and use arrow keys to extend the path.
Consider edges and nearby pairs first, but do not always choose the shortest route. Draw from one letter to its match, then release. Detours may be needed to fill the board.
Start at the green light and trace all white lights exactly once. Visited white lights turn cyan; unlit cells remain blocked.
If all pairs connect but gaps remain, redraw a route through the empty area. Retrace while drawing to shorten a line; Escape cancels the current edit.
Hold the green start and visit adjacent cells continuously. Releasing, leaving the board, revisiting a cell, or cutting off the remaining region resets the path. Time keeps running until you press Restart.
No. Every pair must connect and all 25 cells must be covered. Paths cannot share cells or pass through differently colored endpoints.
Retrace a line to shorten it, or start at an endpoint to redraw that color. Releasing an unfinished line restores the previous complete connection.
Endpoints also carry matching letters A–E. Arrow keys and Enter/Space provide a keyboard alternative to dragging.
Each puzzle lights up 14–23 target cells, with one green light marking the required start. Begin there and trace every white light once using adjacent horizontal or vertical steps. Unlit cells are blocked. Releasing, leaving the board, repeating a cell or reaching a dead end resets the path. Restart retries the same puzzle; Next opens another level.
Single Stroke offers 13 starting-point exercises; Connect and White Lights each offer 120 levels. All puzzles are generated from valid paths. White Lights increases its light count every 30 levels. Uniqueness and strictly increasing difficulty are not guaranteed.
