Onet: Monster Book

Welcome to Onet: Monster Book, where a real adventure begins for everyone who loves to search, connect, and win! Open a huge magic book where hundreds of funny monsters with the funniest faces live. Some make funny faces, some bulge their eyes, and some make such grimaces that it's impossible to keep from laughing! They are all stuck between the pages, and only you can help them meet their twins and break free. The further you flip through the book, the more monsters, bright effects, and unexpected challenges appear. Each level is like a new page of fun, where everything sparkles, shimmers, and beckons you forward. Pay attention, train your memory, act quickly and stubbornly. Then you will surely become the champion of this crazy book. Get ready to win and show all the monsters who is the master of connections here.
How to play?
Now let's figure out how to play and what you need to achieve. On the screen, you will see many cards with monster faces. Your task is to find identical pictures and connect them with a line. But there is a trick: there should be no other cards between them. If the connection is possible, the pair disappears, and you get points and open the way forward. The goal of the game is to clear the entire field and complete the level as quickly as possible. With each new task, there are more monsters and the field becomes more confusing. But don't worry. There are magic hints: you can shuffle the cards, open one matching pair, or add time. Play carefully, collect combos, and earn rewards. Each level you complete is a step toward unraveling the entire monster book. Go ahead, hero! May luck, speed, and attentiveness be on your side.
