Place blocks to break down the tower and save your friends! Click on a block to pick it up and move your mouse to where you want to place it. Press W to flip the block and press E to rotate it clockwise. You want each cube to perfectly fit into the tower. If the block is visible when fitting it, that means it can fit perfectly. Once you're ready, click to place the block!

If you make a perfect fit, it's a Trenga! If the block doesn't fit, it will appear like a shadow. If you place the block without it perfectly fitting, some cubes from the block will float away. You have a limited number of imperfect tries, listed at the top of the screen. If you lose too many cubes, it's game over!

To clear out the rows, each row on every side of the tower must be completely filled in. Press Q or R to rotate your view of the tower to try to find an opening for your block.

When a level has a treasure chest, that means you can unlock a buddy! Each buddy has a special ability that can either improve your score or provide you with a power-up. If a buddy has a powerup, there is a cooldown period where they will not be able to use the powerup for some time. When you start a level after rescuing a buddy, you can decide which buddy you would like to have in the level with you. Use your mouse to hover over each buddy to see their ability, then click on the buddy to include them in the level.

Each level has three challenges to complete. Complete them all to earn all the stars and a higher score!

In later levels, there will be special blocks in the tower. Bomb blocks must be destroyed in a certain number of turns, or the bomb will explode and create holes in the tower. Green blocks in a tower do not need to be filled.

If you finish the main story, play Survival Mode to see how high you can score!
