Overview
Drag the bottom cube left or right and let go. Matching numbers merge into the next one, so aim high. Works offline.
Stackmelt is a 3D cube-merging puzzle played in a tall, phone-style column. A numbered piece waits at the bottom of the lane. Drag it left or right and let go, and it shoots up into the box, where cubes with the same number melt together into the next number: 2 and 2 make 4, 4 and 4 make 8, and so on. Your score is shown at the top, with a button to pause and one for sound. The box fills up as pieces pile in, so every shot should land on a cube that matches it. When they reach the top the game is over and a screen tells you whether you beat your high score. It is an easy game to start and a hard one to master: drag, release, merge. Everything is stored inside the extension, so it works offline, asks for no permissions and collects nothing. Installing opens two tabs, once: the game, and this game's page on yesthisgame.com, the developer's own website. More from us: https://yesthisgame.com
