Start at S, finish at G, and visit every colored tile exactly once. Turntrail is a puzzle about finding a single connected route.
Begin with a small board. As turn markers and straight markers appear, each step asks you to think a little further ahead.
A PHOTO AT THE END OF YOUR PATH
In Photo mode, each tile you visit reveals part of a picture. Solve the puzzle to see the full photo in the same place as the board, with a gentle lift and a background inspired by its colors. You can switch back to the standard board in Settings.
Start with 100 bundled photos. While you play online, new photos download in the background. A photo is never assigned to another new puzzle, and saved photos remain available offline.
Revisit completed puzzles in Album. Tap a photo's heart to keep it in Favorites.
HOW TO PLAY
• Drag your finger or tap an adjacent tile to extend your path.
• At a turn marker, turn 90 degrees. At a straight marker, keep going in the direction you entered.
• Visit every colored tile before entering G.
• Tap an earlier tile to go back. Lift your finger whenever you like and continue where you left off.
24 LEVELS, THEN KEEP GOING
Learn the rules through 24 main levels, then try generated puzzles in Endless. You can also enter Endless before finishing the main levels.
Choose Auto to let the difficulty change as you play, Normal for 4×4 boards, or Hard for 5×5.
For a larger board, open Choose a Size and select any size from 6×6 to 12×12. Zoom in on boards of 7×7 and larger. Each new puzzle keeps your chosen size.
In Endless, save a skipped puzzle with its unfinished path and resume it later. After solving one you have resumed from Skipped puzzles, Next takes you to a new puzzle. You can also return to recent puzzles. Previous, Restart, and Skip are together on the play screen.
TAKE YOUR TIME
There is no timer. Connect tiles in quick succession to hear the notes rise; pause to think and the pitch resets. A short sound welcomes each new puzzle, and a soft melody with a lingering finish marks each clear. Sound and haptics can each be turned on or off.
After solving a puzzle, replay your route from S to G, one step at a time.
A HINT WHEN YOU WANT ONE
Finish watching an optional ad to use a hint for your next step. If your current route leads to a dead end, the hint takes you back to a position you can solve from. Ad-supported hints require an internet connection.
PICK UP WHERE YOU LEFT OFF
No login is needed. Puzzles can be played offline, and your current path and progress are saved on your device. The app supports English and Japanese and follows your iPhone's language settings.
