Every year a few puzzle formats break out on the mobile stores and then get copied, reskinned and improved by thousands of developers. If you want to publish a puzzle game that players are already searching for, it makes sense to start from a format that is trending and from complete Unity source code for it. Below are the puzzle formats getting the most attention in 2026, how each one works, and the projects in our store you can build from.
1. Screw and nuts-and-bolts puzzles
Players unscrew bolts in the right order to release metal or wooden plates, and must plan ahead because a wrong move can block the board. The physics and the satisfying sound of each screw make these games very watchable, which helps on social media.
- Screw and Bolts Take Off Unity Source Code: bolts, screws and metal plates with logic-based ordering.
- Wood Nuts and Bolts Puzzle Unity Source Code: the same idea with a warm wooden theme.
2. Car jam and bus escape puzzles
A crowded parking lot or a road full of buses, and the player must move vehicles out in the right order, often matching passenger colors. These games combine traffic puzzles with color sorting.
- Bus Out Mania Unity Source Code: plan routes, sort passengers by color and clear the traffic jam.
- Park Match Car Jam Puzzle Unity Source Code: car parking, matching and traffic jam mechanics with colorful vehicles.
3. Tap-away and arrow escape puzzles
Each piece can only move in one direction. Tap it and it slides away, unless another piece is in the way. The board looks simple, but later levels need careful planning, which keeps players engaged for a long time.
- Tap It Away 3D Block Puzzle Unity Source Code: a Unity 2022.3 project with 150+ levels and an editor scene for building more.
- Arrow Out Escape Puzzle Unity Source Code: arrow-based escape puzzles with 1000+ handcrafted levels and 350+ shape levels.
4. Block puzzles and number merge
Block puzzles never really went away, and new versions with jewel styling, combos and number merging keep climbing the charts. They appeal to all ages and support very long play sessions.
- Block Blast Jewel Unity Source Code: a colorful block puzzle inspired by Block Blast and jewel games.
- Block Puzzle World Classic Unity Source Code: the classic relaxing block-filling format.
- X2 Blocks 2048 Number Unity Source Code: drag, drop and merge numbers in a 2048-style block game.
5. Sort and pixel puzzles
Sorting by color is still one of the strongest casual mechanics, and newer games combine it with pixel art that is revealed as the board is cleared.
- Ant Flow Colony Sort 3D Unity Source Code: built with Unity 6, with a five-slot tray and pixel artwork revealed at the end of each level.
- Loop Diamond Sort Unity Source Code: cubes from a 32×32 pixel grid travel on a conveyor and are collected by color.
- Magic Water Sort Unity Source Code: the classic water sort, also a good base for a ball sort game.

6. Brain and logic puzzles
Logic games attract a loyal audience that plays every day, and they are easy to extend with new level packs.
- Meowdoku Brain Puzzle Unity Source Code: a cat-themed logic puzzle with ads integration, power-ups and a skin shop.
- Hexa Light Connect Unity Source Code: rotate hexagon pieces to guide light and connect every lamp.
- 1Line One Stroke Puzzle Unity Source Code: connect every dot with one continuous line, with a level creator included.
How to choose the right trend for your next game
- Search the store. Look up the format on Google Play and check how many recent games exist and how strong the top results are.
- Find your angle. A new theme, a new art style or a twist on the rules is what makes a reskin stand out.
- Check the content. Puzzle players finish levels quickly, so prefer templates with many levels or a level editor.
- Plan monetization early. Rewarded ads for hints, undo and extra moves are the standard in every format above.
