Screw Spark: Bolt Sort Puzzle

Overview
Screw Spark: Bolt Sort Puzzle is a free puzzle game from SOHI GAMES that turns a familiar workshop idea into a calm, colour-based sorting challenge. Each board is covered with bolts in different colours, and the goal is to remove every bolt in an order that keeps the board workable. The presentation is bright and clear, with bold colours and large, readable shapes, so it is simple to see at a glance which bolts are available and which colour slots are open. The game is rated Everyone on Google Play, requires Android 7.0 and up, and was released on 8 October 2026, with version 1.0.6 updated on 26 October 2026. On the live listing it holds 4.9 stars from 955 reviews and carries a 10K+ downloads badge. It is free to install, contains ads, and offers in-app purchases priced from $1.99 to $99.99 per item. The Play Store web page does not display a download size, so no size figure is claimed here.

Gameplay
The core loop is built around tapping and matching. A bolt can be taken from the board and placed into a slot of the same colour. When a slot group is complete, that colour clears, freeing space for later moves. A level ends when every bolt has been removed, but a poor sequence can leave bolts with nowhere to go, so the order of moves matters more than speed. Early boards introduce the idea with a small number of colours and generous space. Later boards add more colours, tighter layouts, and boards shaped like animals, objects, and letters, which change where bolts sit and how easily they can be reached. There is no rush to finish a move in a set time, which lets players pause, look at the whole board, and test a plan in their head before committing to it. Boosters appear as a help when a board becomes crowded, although thoughtful planning usually solves more problems than a booster alone.

Features

• Tap controls that keep the focus on choice rather than speed or precision.
• Colour matching that is clear at a glance, even on busy boards.
• A steady rise in difficulty, from short introductory boards to layered layouts.
• Boards in varied shapes that change the route through each level.
• Boosters for moments when space runs short or a sequence stalls.
• A calm visual style with bright colours and tidy, uncluttered boards.
• Regular level progression that rewards planning rather than fast reactions.
• Compatibility with Android 7.0 and later devices, as stated on the listing.

Tips for new players
Start by scanning the full board before tapping anything, and note which colours are blocked by bolts on top of them. Clear a colour only when you can see a useful next move, because an early clear can fill slots that a later colour needs. Keep at least one free slot in reserve whenever possible, so a single awkward bolt does not trap the board. Work from the most crowded areas outward, since bolts buried under others often decide which moves are safe. If a level stalls, step back and look for a different first move rather than repeating the same sequence. Use boosters sparingly, saving them for boards where space, rather than understanding, is the real problem. Finally, treat a failed board as information: the move that caused the jam usually points to the better order for the next attempt.
