Play Stack Up Online
Stack Up is a game where you see little piles of colored blocks on a grid. Each pile has a color and a number, and you move them to join piles that look the same. When you link a group in a line, that whole group disappears and you gain points. The game tells you what you need to do, like reach a certain score or clear enough stacks before your moves run out.
You tap and think about where a block should go next. A short line gives you a small boost. A long line feels much better because the board opens up and you get more points at once. After each move, new blocks show up and the picture changes, so you look again and plan a fresh path. Early stages feel simple and let you learn without pressure. Later stages ask for smarter moves and teach you to wait for better chains.
The screen uses bright colors, so you spot matches without effort. The rules stay the same from start to finish, which helps kids feel safe while the puzzles grow harder in a slow way. Stack Up helps children practice number reading, pattern finding, and planning ahead. It feels calm, not loud, and gives a nice sense of progress when a long line of stacks clears in one smooth move.
