Bar Sort
Read full descriptionHide full description
Bar Sort is an addictive color sorting puzzle game that is as relaxing as it is challenging. If you love games that test your logic but don't stress you out, this is the perfect game for you. The goal is simple: sort the colored bars into the tubes until each tube holds only one color and all bars of the same color are in the same tube. It sounds easy, but you'll need to plan your moves carefully to solve increasingly complex patterns.
must be one
Read full descriptionHide full description
must be one is a number puzzle built on a single rule โ the one in its name. A grid of numbers. Four operators. Combine neighboring tiles with arithmetic and collapse the whole board down to a single 1. That's the entire game: all becomes one. It reads as obvious for about three moves. Then it doesn't. - One rule, no filler โ no twenty-minute tutorial, no menus to dig through. You understand it in seconds and spend the rest of your time actually thinking. - Always solvable โ every stage is generated so that a solution is guaranteed to exist before you ever see it. If you're stuck, that's on you, not the board. - A climb that keeps widening โ early stages stay in single digits; later ones open the range up and the arithmetic gets meaner. - Free, and quick to pick up. One stage on the train; look up an hour later. From office-canard โ a one-person studio making small, system-first games. If this one gets its hooks in, there are more small games where it came from.

Verdict
The clearest difference is in-app purchases: must be one at none against Bar Sort's 4. Bar Sort's advantage is ads (none vs shown). On price, device support and iOS requirement there is nothing between them.
