## What is Boltfall?

Every plate hangs on its bolts. Unscrew them in the right order and the steel comes crashing down.
Sort colours into a three-slot holder — three alike clears it, one wrong bolt jams it.
Easy to start, genuinely tricky to master, and satisfying every single level.

HOW IT PLAYS
• Tap a bolt to unscrew it. Free every bolt on a plate and the plate falls away.
• The holder has three slots. Three bolts of one colour clear a set. Mix colours and you jam.
• Deep bolts need several full turns — commit to one and it reserves a slot.
• Covered bolts hide under layered steel. Drop the plate above to reach them.

WHY YOU'LL STAY
• 150 hand-tuned levels across six workshops, from Toolbench to Foundry
• A real difficulty curve: think two moves ahead, not just match colours
• Undo, hints and boosters when you're stuck — never pay-to-pass
• Short levels, one-hand play, works offline
• Colour-blind friendly: every colour has its own head shape

No forced video ads. Ads only play when you ask for a bonus.
