2. Observe the hexagon-shaped board composed of multiple cells forming lines both horizontally and diagonally.

3. At the bottom of the screen, you will see three differently shaped block pieces.

4. Drag and drop one of the block pieces onto the board, placing it in an available space.

5. Your goal is to completely fill a line—either horizontally or diagonally—with blocks.

6. When a line is fully filled, it disappears from the board and you earn gems.

7. After placing a block, a new piece will generate in its place until all three have been used.

8. Once all three blocks are placed, a new set of three appears.

9. Strategically plan your moves to avoid running out of space on the board.

10. The game ends when there is no room left to place any of the current block pieces.

11. Use gems earned during gameplay to activate boosters when needed.

12. Boosters can help by clearing blocks from the board or changing the available block pieces.

13. Monitor your board carefully and think ahead to maximize space and clear more lines.

14. Continue playing to beat your high score and collect more gems.

15. Enjoy the summer-themed visuals and addictive puzzle challenge of Hexa.
