What we like
- Simple, familiar sorting idea that is easy to pick up
- Free and rated Everyone
- Short levels suit quick breaks
Watch out for
- Has ads
- Includes in-app purchases
- Very similar to other sorting games, so it may feel repetitive
Each level gives you bolts stacked with colored nuts. You move nuts from one bolt to another, matching colors, until every bolt holds nuts of a single color.
It plays like other sorting puzzles but with a nuts-and-bolts theme. Levels begin easy and get trickier as more colors and fewer free spaces appear.
The game is free and supported by ads and optional purchases. It is a fit for players who like unwinding with a sorting puzzle and don't need much story or variety.
