Block D

Read full description

Come and design your own blocks. This is a cube game where you can design your own shape, I believe it will be a good choice for block lovers. Traditional block games only have a fixed and small number of forms. Let's make something different. We can not only design the shape of the block by ourselves, but even have more than 7 shapes at the same time. Now you are no longer limited by the border, the block can pass through the left and right walls at will, and maybe find a better position through the wall. In terms of game rules, we have borrowed traditional rules, such as moving, rotating, rotating, and eliminating, while retaining most of the gameplay and adding new rules. Even you can customize the size of the site, with greater freedom and fun. Hurry up and try the brand new game, I believe it will be a very interesting journey.
