In Color Block Jam, your goal is to match and stack blocks of the same color. You need to eliminate blocks from the board by forming groups of three or more, which helps to clear space and score points.

Power-ups can be activated by clearing specific combinations of blocks. These special boosts can help you clear more blocks at once or eliminate an entire color from the board, making it easier to progress through levels.

To increase your score, focus on creating larger matches. Clear multiple lines at once and utilize power-ups strategically. Plan your moves in advance to maximize the matches you can create, leading to higher scores.

Challenging levels require careful planning. Here are some strategies: 1. Prioritize clearing colors that dominate the board. 2. Utilize power-ups smartly in difficult spots. 3. Look for hidden combinations for more matches. 4. Always think a few steps ahead to anticipate block movements.

To unlock new levels, you need to complete the current levels with a minimum score requirement. Pay attention to the objectives listed for each level, and strive to complete them efficiently to progress further in the game.
