STACK.it
Try STACK.it, a unique puzzle game. Slide numbered blocks, merge matching piles, build massive point chains, push past 2048, and beat your high scores.
STACK.it Overview
STACK.it is a number puzzle game built around moving and merging small stacks. Slide matching piles together and watch them combine into a larger value. Reach 2048, then continue playing to create even bigger numbers.
Each move changes the whole board. A useful merge can create space, while a careless move can leave too many piles trapped together. The main challenge is to keep the grid open long enough to build strong combinations.

Sliding and Merging Guide
Sweep your numbered blocks across the grid layout. Matching piles combine into a thicker column upon contact. Every successful merge pushes your numerical value higher.
Plan your moves to trigger chain reactions across multiple rows. Combine large sets of ten or fifteen stacks in a single move for peak scoring.
Watch out for deadlocks when your board fills up with no moves left. Activate your free helper bonus to shift blocked pieces whenever layouts jam.
There is no need to stop after reaching 2048. You can keep merging and push your numbers higher. The round only ends when no empty cells remain.
How to Plan Combo Chains
Avoid placing large number piles randomly across the middle of the grid. Isolated stacks can block open space and make future chains harder to create.
Anchor your highest-valued stack firmly in one bottom corner and build ascending columns right beside it.
Leave specific lanes open for incoming sliding tiles to ensure your board never locks up prematurely.
