Hey everyone, thanks for checking out Oonlu! I'm the developer behind Oonlu. It's a collection of 17 mini games you can play offline, all in one app. There are classics like Minesweeper, 2048, and Domino, plus Match 3, word puzzles, merge games, and a few arcade games. I wanted to keep these games together, so you don't have to download a different app each time. If one gets boring, pick another. Oonlu also has online leaderboards. Play offline, then go online to compare scores with other players. If beating your own record isn't enough, there's always someone else's score to chase. HERE ARE THE 17 GAMES • Gamento: Match colorful marbles and plan your next move in this puzzle game. • Sudoku: Fill the grid with numbers and solve classic Sudoku puzzles. • The 5 Lines: Move colored balls into matching lines and try to beat your best score. • Ketch Saga: Match colorful animals, complete objectives, and work through the Match 3 levels. • Minesweeper: Find the safe squares, mark the mines, and clear the board without hitting one. • Denonet: Connect matching tiles and clear them from the board. • FruitMerge: Drop fruits, merge matching ones, and try to make the biggest fruit before you run out of room. • Blocky Stack: Stack blocks carefully and see how far you can get. • Knife Shot: Throw knives at a spinning target without hitting the ones already stuck there. • Jecash Merge: Merge money from small amounts all the way up to bigger values. • 2048: Slide numbered tiles together to reach 2048, or keep going and beat your best score. • Stack Block: Line up the blocks, get your timing right, and build as high as you can. • Domino: Play a round of the classic tile game without leaving the app. • Wovicle: Connect letters to find words and complete each word puzzle. • Sand Block: A block puzzle with falling sand that changes the way you clear the board. • Maze Block: Find your way through a maze and reach the finish. • Tower Block: Build a tower one block at a time and try to keep it standing. OFFLINE GAMES WITH ONLINE LEADERBOARDS You don't need Wi-Fi or mobile data to play Oonlu's main games. I wanted them to work when you're traveling, waiting somewhere, or just don't have a good connection. With a connection, check the leaderboards, compare scores, and climb the rankings. The competition is there when you want it, and you can still play offline whenever you like. Online leaderboards, advertisements, and in-app purchases need internet access. PUZZLES, BRAIN GAMES, AND MORE Minesweeper, Sudoku, and 2048 are for logic and number puzzles. Wovicle is for word games. Ketch Saga, Denonet, Gamento, and The 5 Lines offer different matching challenges. FruitMerge and Jecash Merge are about combining things, while Knife Shot and Stack Block are about timing. Not everything has levels to finish. Some games are endless, so you can keep playing until you make a mistake, then start again and try to do better. You can play for two minutes or stick with one game for much longer. That's up to you. FREE TO DOWNLOAD AND PLAY All 17 games are included in the free version. Oonlu has ads to help cover development and maintenance, but there's an optional purchase to remove automatic ads. An Oonlu Bundle is also available. Some games let you watch a rewarded ad to revive and continue after losing. That's optional, and rewarded ads may still be available even after you remove automatic ads. A NOTE FROM THE DEVELOPER Oonlu is made by one person. I work on the games, draw the artwork, and fix the bugs too. There's a lot I still want to improve, and more games I'd like to add in future updates. I also want to know when something doesn't feel right. A confusing level, a button that's hard to tap, anything like that. If you try Oonlu, tell me which game you keep coming back to, or what I should fix. I read the feedback, and it helps me decide what to work on next. Thanks for giving my game a try!
