The cube has to reach the goal, but this is only possible if the gate is active. So it’s push, connect, disconnect - and above all: act tactically wise. The functions of DADI are simple, but the puzzles will make your brain sweat. From level to level, the puzzle worlds become more complicated, the challenge gets bigger, and often there is not just one correct solution. The game contains no ads and no in-app purchases. Pay once for DADI and enjoy.

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.

Verdict
The clearest difference is rating: Zerko at 4.9 against Dadi's 4.7. Dadi's advantage is update cadence (every 9 days vs every 3 weeks) and ratings volume (72 vs 14). On price, review sentiment, ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Dadi costs $2.99 and Zerko $2.99 up front. Neither carries in-app purchases, so what you see is what you pay.
Zerko holds the better App Store score, 4.9 against 4.7. That said, the two scores are not equally well evidenced: Dadi has 72 ratings behind it against 14, so its average is the more settled of the two. Written reviews complicate that: 95% of Dadi's written reviews are positive against 93% of Zerko's, so the app with the better star average is not the one people write more warmly about.
Dadi ships an update every 9 days, Zerko every 3 weeks. The most recent releases landed on September 30, 2026 and September 11, 2026 respectively.
