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.

About

PushRooms

Features
Read full description

PushRooms is a Sokoban-style box-pushing puzzle game set across forest, sea, night and winter worlds. Push boxes onto their destinations, keep a route open, and reach the exit. Every room is a new logic challenge: which box should you move first? PLAN EACH PUSH Think about box placement, movement order and the space you need to move. A box in the wrong spot can block your route. Use Undo to rethink your moves and try another approach. EXPLORE FOUR WORLDS Travel through forest, sea, night and winter stages. Discover puzzles with holes, spike switches and direction-restricted boxes, then take on boss rooms and rescue princesses. TAKE ON BONUS CHALLENGES Unlock three star-catching bonus challenges after the first boss. Complete them to earn spare hints for your adventure. PLAY YOUR WAY Choose joystick or directional button controls. Rewarded ads provide movement hints. Interstitial ads are used to refill Undo credits and restart attempted, uncleared stages. English and Korean follow your device language. No account or sign-in is required; progress is stored on your device. WHAT KIND OF GAME IS PUSHROOMS? It is a grid-based box-pushing game inspired by Sokoban, also known as the warehouse keeper puzzle. You solve each room by planning how boxes and paths interact, then finding your way to the exit. Think ahead, make your move, and open the way.

Verdict

The call

The clearest difference is price: PushRooms at Free against Zerko's $2.99. PushRooms also leads on update cadence (every 2 days vs every 3 weeks). Zerko's advantage is ads (none vs shown) and iOS requirement (12.0 vs 15.0). On in-app purchases and device support there is nothing between them.
