Plain rules for playing fair.
Using the game
The Plank Keeper is provided by Portalship for personal, non-commercial entertainment. You may install and play it on your own devices. Please do not copy, reverse-engineer, or resell the game or its levels.
The leaderboard
The daily leaderboard is for friendly competition. Do not use bots, modified apps or any other trick to post results you did not earn. We check every submitted result against the rules of the puzzle and may remove results, or block devices, that look cheated. Display names are generated for you; if we add custom names, they must not be offensive, and we may change or remove names that are.
Purchases
Optional items (such as hints, skips and streak freezes) are virtual goods with no cash value. Purchases are handled by Apple or Google and are subject to their refund rules. Items cannot be transferred between accounts.
Availability
We try to keep the game and the daily puzzle running, but we do not promise they will always be available. Features, levels and the leaderboard can change or stop.
No warranty
The game is provided "as is". To the extent the law allows, Portalship is not liable for any loss arising from using it. Nothing here limits rights you have under the law where you live.
