Think about sudoku, but reinvented! This game has just a few simple rules: You have to fill a 4x5 grid with numbers from 1 to 5, ensuring that each row and column won't have duplicates and that the sum of each row’s numbers gives the result on their right side. Also, you must insert all five numbers (1,2,3,4,5) into the two colored sections on the grid. Each puzzle has a unique solution. It's relaxing, but still pretty challenging. If you want to spice up the challenge, play • zenku • in YinYang mode and complete the puzzles within 2 minutes! The first 50 levels are free, with some ads here and there in case you'll ask for a hint (bulb button). You can unlock extra 50 levels and remove ads with a single In-App purchase. Will you complete all the 100 zenku puzzles? _________________________________ Frank Eno (aka XSGames) is an indie game dev from Italy.

Peekaboo– A Whimsical Hide-and-Seek Adventure (No ending phrase version) In a quiet, giggling forest, five adorable creatures are hiding behind soft, leafy bushes. They’ve spread out across the woods, waiting for someone clever enough to find them. In Peekaboo, you are the seeker! Your mission? Use 15 magical taps to discover all the hidden characters! Here’s who’s hiding: Two tiny ones taking up 1 bush each, two playful ones hiding across 2 bushes each and one big, cuddly creature sprawled out over 4 bushes. That’s 5 friends taking up a total of 10 forest tiles. But don’t be fooled—just because you have 15 chances, doesn’t mean it’ll be easy! Every tap counts, and smart choices lead to victory. There are no rounds. No second chances. Just one whimsical challenge to prove your forest-finding skills! The faster you discover all the hidden creatures, the higher your name climbs on the global leaderboard. Peekaboo is a delightful mini adventure for all ages—easy to start, fun to master, and filled with charm.

Verdict
The clearest difference is in-app purchases: PeekaBooka at none against zenku's 3. PeekaBooka also leads on iOS requirement (13.0 vs 15.0). zenku's advantage is ads (none vs shown) and update cadence (every 3 months vs every 7 months). On price and device support there is nothing between them.
