Numbertris: Number & Block

Number-tris is a new 3D block puzzle game that adds level rules expressed by numbers to the classic block puzzle game. The number displayed on the block indicates the level of the block, i.e. the number of floors. For example, a block marked with the number 1 equals a single-story building, a block marked with the number 2 equals a two-story building, and a block marked with the number 10 equals a 10-story building. The goal of the game is to score the highest score by clearing as many blocks of the highest level as possible according to the rules of the familiar block puzzle.

1. 11 types of number-rominos, consisting of 1 to 4 square blocks, appear randomly.

2. Place the given number-rominos on a 9*9 grid. It can be rotated 90 degrees to place it in any orientation you want.

3. Blocks can be eliminated by creating lines vertically or horizontally, or by filling a 3*3 grid.

4. When a certain number of blocks are eliminated, the level of the appearing blocks increases. To get rid of a block with a larger number, of course, you need an equal number of blocks. There is no limit to the level of blocks.

5. Bomb blocks completely destroy all levels of blocks on a 3*3 grid. Make good use of the bomb blocks to free up space and escape the crisis.

6. Each time you place and clear a block, you score points. You can get a bigger score by clearing multiple lines in one operation or by successfully clearing blocks in a row.

7. Score the highest score and make your name on the world leaderboards. Develop your own strategy to become a world-class Number-tris master.
