Boltfall: Screw Puzzle 3D

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.
