Onet Monster Book is a fast-paced tile-matching puzzle game where you connect pairs of identical monster tiles.
Played in your browser with a mouse, this casual game challenges you to clear a board full of colorful creatures by linking them with a path that has no more than two 90-degree turns, similar to classic Mahjong Connect titles.
The core mechanic of Onet Monster Book revolves around pathfinding. You can't just click any two matching tiles. To successfully remove a pair, you must be able to draw an imaginary line between them that takes a maximum of two turns.
Think of it like this: the line can go straight, make one L-shaped turn, or make a Z-shaped or U-shaped path with two turns. Crucially, this path cannot pass through any other tiles on the board.
The easiest matches are tiles directly next to each other or along an open edge.
As you advance through the levels, the layouts become more complex and the board gets more crowded. This makes finding valid paths a greater challenge, especially with the timer ticking down.
You'll need to develop a sharp eye for spotting potential connections that aren't immediately obvious.
The game provides helpful tools like hints, which reveal a valid pair, and shuffles, which rearrange all the remaining tiles on the board. Using these power-ups strategically is key to overcoming the most difficult stages and clearing the entire monster book.
You can play Onet Monster Book for free directly in your web browser. There's no need for any downloads or installations, making it easy to start playing instantly.
Because it's a lightweight HTML5 game, it runs on most devices and can be accessed on school or work networks that allow gaming sites.
The main goal in Onet Monster Book is to clear the entire board of all monster tiles before the timer at the top of the screen runs out.
Use your mouse to play. To make a match, left click on one monster tile and then left click on its identical twin. If the connection is valid, the tiles will disappear.
A connection is only valid if the path between the two tiles is clear and uses two or fewer 90-degree turns. Tiles that are right next to each other can always be connected.
When you get stuck, you can use the Hint button to reveal a possible match or the Shuffle button to rearrange the remaining tiles on the board. Complete a level to move on to the next, more challenging layout.
Scan the Perimeter - Always check the outer edges of the board first. Tiles here have more open space around them, making them the easiest to match and clear.
Look for Adjacents - Before searching for complex paths, do a quick scan for any identical tiles sitting right next to each other. These are free matches that clear space instantly.
Plan Your Path - Mentally trace the line between two potential matches before you click. This saves time and prevents you from making invalid attempts when the clock is ticking. Save Your Hints - Hints are limited.
Try to save them for the end of a level when the board is cluttered and you're running low on time. Shuffle Strategically - Don't use the shuffle button just because you can't find a match immediately.
Use it as a last resort when you are certain no more moves are available.
