Thanks for playing The Grid Master! If you have a question, a bug to report, or a suggestion, we’d love to hear from you. Most emails are answered within a few business days.
When reporting a problem, it helps to include:
Tap any cell of the grid to place your first number. Then keep jumping from the last cell you filled, following one simple rule:
You can never land on a cell that is already numbered or outside the grid. Each jump writes the next number, and the goal is to fill the whole grid without ever getting stuck.
Six sizes, from 5×5 up to 10×10. Choose one from the home screen; a star appears next to every size you have completely filled.
The game tells you when there is no possible jump left. Your score is the number of cells you filled, and your best score for each grid is kept. Use Undo to take back your last jumps, or Restart to begin the grid again.
Start from a corner, work the edges before the centre, and avoid leaving isolated cells behind you — a cell that no jump can reach is what ends most games. On the larger grids, it helps to think in terms of the pattern your jumps trace rather than one move at a time.
Yes. Your completed grids, best scores and the game in progress are stored locally on your device and reload automatically when you reopen the App. They are removed if you uninstall it.
