About Block 21
The playing field in Block 21 will be filled with colorful square tiles with numbers on them. The goal is to get a tile with the number twenty-one. Look for tiles with the same values on the field; they should be nearby and their number should not be less than three. By clicking on a group, you will receive one tile with a number one higher at the location where you clicked. This way you can get the final tile and complete the Block 21 game, but it's a long way off. You will enjoy a calm and colorful relaxation game.
