Sure, here's a step-by-step guide on how to play Lumeno:

Start the game by looking at the grid of blocks of different colors.

Your goal is to connect at least two blocks of the same color by drawing a path between them. The path can be horizontal, vertical, or diagonal, but cannot overlap with other blocks or paths.

When you successfully connect two or more blocks of the same color, they will disappear from the grid and new blocks will fall down to fill the empty spaces.

You can continue to connect blocks of the same color to score more points and clear the grid.

As you progress through the game, the levels will become more challenging, with more blocks to connect and new colors to add to the mix.

To make the game even more exciting, you can compete against other players to see who can score the most points or complete the most levels.

The game also includes special features such as "wildcard" blocks that can be used to connect different colors, and power-ups that can help you clear the grid more quickly.

The game ends when the blocks reach the top of the grid and there is no more space for new blocks to fall. Your final score will be based on the number of blocks you connected and the length of the paths you created.

And that's how you play Lumeno! Keep in mind that the game may have additional features or variations depending on the specific version you are playing.
