About this game
Some call it reverse sudoku, while others call it a nullification game, but it's Zerko - a puzzle game filled with shapes, numbers, and a straightforward goal: make every number zero.
To achieve this, you need to strategically place blocks of various shapes and values so that the numbers on the board effectively "remove up" to zero.
Like all my games, this one too is about relaxation... Just chill. There are no points, no time pressure, no data collection, no in-app purchases, no ads, no nonsense ;) My only hope is that you'll enjoy it and that I'll be able to add new content and levels for you in the future.

As Rainbow Train games go, it's not my favorite, but as a basic math puzzle, it's pretty neat. In keeping with your expectations, it's quite nicely made, with pleasant sounds and gameplay. The offset between the position of your finger and the block is a little frustrating, makes it hard to play in portrait, but it's still a nice, pleasant little game worth your time.

another great masterpiece of minimalist puzzles. I usually am terrible at math puzzles games and I avoid them. but as usual, rainbow train does an excellent job easing players into the game via small easy puzzles that gently teach the player the game mechanics. then slowly increasing the difficulty level but it never feels too difficult. this game was very easy to learn and very enjoyable from start to finish. it helps that the game auto calculates the math for the player. thanks!

pretty short game, don't think I spent more than maybe 60-70 minutes in total but it was a fun game. its a bit like a mix between sudoku and laying puzzles, with a relaxed difficulty level. no annoying ads or credits you need to buy which is always appreciated 👍
