Boltwright: Screw Puzzle

Unscrew the bolts, sort them by color and watch the wooden planks tumble. Boltwright is a calm nuts and bolts puzzle where every cleared board builds a piece of a wooden toy.

120 handcrafted levels, no timer, and every level is proven solvable without boosters.

HOW TO PLAY
• Wooden planks are stacked in layers and held by colored screws.
• You can only unscrew a screw that no plank is covering.
• Each screw goes into the box of its color: two boxes are open, three slots each, and you can see which boxes come next.
• No matching box? The screw waits in a 5-slot tray. If the tray fills up, the level is lost.
• A plank with no screws left falls. Planks swing on their last screw before they drop, with real physics.
• Clear every plank to win.

GRANDPA'S WORKSHOP
You have reopened your grandpa's old wooden toy workshop. Each solved board assembles part of a toy: a rocking horse, a toy train, a birdhouse, a music box, a sailboat, a windmill, a toy truck, a carousel, an airplane, a dollhouse, a lighthouse and a grandfather clock. Finished toys go up on the workshop shelf, and short letters from grandpa wait between chapters.

FAIR BY DESIGN
• Every level is checked to be solvable without boosters. No rigged boards.
• No timer. Think as long as you like.
• Ads are kept in check: none in the early levels, never right after a failure, only between levels, and no banner ads.
• Remove ads with one purchase, and also get booster rewards without watching videos (daily limit).
• Colorblind-friendly: every screw shows a number and a symbol as well as a color.
• Plays offline.

BOOSTERS FOR TRICKY BOARDS
• +1 slot: an extra space in the tray
• Undo: take back your last move
