Boltumi: Screw Puzzle
Unscrew. Unwind. Play offline.
Free · In‑App Purchases
Pull a screw. Make room. Let gravity finish the job. Discover 600 puzzles in wood, ice, metal and leather, with free Undo.
One screw can change everything.
Pull it out and put it back into a free hole. The plates react at once: a plate left on one screw swings, a plate with none falls off the board. Clear every plate. Boltumi is a calm physics puzzle about space, order and gravity.
FOUR MATERIALS TO EXPLORE
Warm wood, slippery ice, heavy metal and grippy leather each have their own board, feel and physics. Metal swings further and bounces; leather grips and stops. Look closely: the next move is not always the obvious one.
START SMALL. THINK AHEAD.
Six guided lessons in the Workshop show you how it works. Then 600 puzzles wait on a painted map. Most levels have a move limit: finish at or under par for three stars. Take your time, try an idea and enjoy the moment it clicks.
CHANGE YOUR MIND FOR FREE
Undo is free and unlimited, and it gives the move back. Every level can be solved without paid tools; they only make it quicker.
HELP WHEN YOU WANT IT
Every new star earns 10 coins. Optional videos give 50 coins each, up to five a day. Coin packs are optional too, and there is no subscription. Spend coins on extra moves, a new hole with the hand drill, removing a screw with the pliers or lifting a plate off the board.
YOUR QUIET PUZZLE BREAK
Play offline, with no account. Only the optional videos need internet. Set music, game effects and navigation sounds separately. Optional reminders come at most twice, after a few days away.
Available in 45 languages. Usage statistics help improve the game and can be turned off in Settings.
