## What is RGB Logic (Buchstabensalat)?

RGB logic is a bit like a colorful, simpler Sudoku (but it can actually be really tricky). Simply arrange the colors so there is one of each in every row and column and the arrangement matches the clues on the outside.

A tutorial gently introduces the rules of the game.

There are 10 brand new free puzzles of varying difficulty every day. 

You can share any puzzle (even with people who don't have the App yet).

There are also modes called 18, 24 and 50 where you have precisely that number of moves and a ticking clock to solve puzzles. Just one mistake and you won't be able to complete the puzzle.

A one off in app purchase unlocks the full set of 20 puzzles every day and the 24 and 50 modes.

### 4/5 — Pretty good but a bit limited

*2024-02-17*

I don’t often pay for apps but I paid for this cute little app expecting to get a bit more than what I got. There’s not that many “Hard” puzzles daily and you don’t always get the hardest ones every day, and even those are not even that hard! It’s a fun concept but I wish there could be bigger boards, and more of them. Surely that wouldn’t be too hard to create? Make it so!

### 1/5 — Love but I paid and it still won't allow me access

*2018-04-12, version 3.1*

How do I get paid access? I purchased and hit restore purchase numerous times and I still get the error when I try to access levels above 10 🤷🏽‍♀️ I want my money back?

### 5/5 — Great game

*2017-10-25*

Really good

### 5/5 — Very Good!

*2016-04-29*

Took a while to understand how all the mechanics in the game works even with the help of the tutorial. When I did figure it out I throughly enjoyed the game to the point where I couldn't get the satisfaction of only playing 5 levels per day, so I brought the extra daily levels. I would highly recommend this game to people who like puzzles and this is a very unique puzzle game!
