27 or Twenty-Seven is a novel puzzle game that enhances spacial and combinatorial thinking. You move colored balloons on a 3D-grid. Adjacent balloons of the same color and size merge to form a balloon of the next higher size. Your goal is to get ever larger balloons. You start on the edges of a cube 2×2×2 grid, with two balloons of level 1 (pink) or 2 (violet). Each time you move or merge balloons, you get another pink balloon. Move and merge away to get a blue (level 3) balloon, then a turquoise (level 4) balloon. Your first goal is a red balloon of level 8. This sounds easy, but can be tricky since you have only 8 positions available. Luckily, you can start over whenever you like. Expert players achieve a red balloon in a few minutes. Even they don't achieve the next goal every time: a full house of 8 different balloons. Once you get tired on the cube, which is in fact a 2×2×2 grid, we have other challenges in store, starting with a 2×2×3 grid, a 2×2×4 grid, and going up to a 3×3×3 grid with 27 possible positions, again in a cube. Now guess where we got our name? While the fundamental rules are the same, winning strategies for each grid vary. The game is easy to learn, and we have a tutorial to teach you. We give you a few opportunities to undo if you make a mistake. You may move and merge balloons by swiping over your touch screen or by pushing buttons. You can also use an external keyboard. You may turn the grid in any direction you like. Buttons can be placed on the right or the left side of screen, or be hidden.

About

Sip & Stack

Features
Read full description

Sip & Stack is an exciting and innovative puzzle game that combines strategic thinking, management, and satisfying mechanics. Take on the challenge of managing dual grids as you race to merge boxes, match drinks, and keep the dock running smoothly. The gameplay is simple yet challenging: Upper Grid: Drinks of different colors advance on the conveyor with each action. Your goal? Prevent them from falling into the hole! Lower Grid: Merge at least three adjacent boxes of the same color to create space for drinks. Larger merges create special boxes that can accept drinks of any color, giving you a strategic advantage. Each level becomes more dynamic as conveyor speeds increase, new drink colors are introduced, and grid sizes expand. Plan your moves carefully to avoid overfilling the dock or losing drinks! Why You'll Love Sip & Stack: Strategic Gameplay: Every move counts—maximize merges, manage space, and keep drinks flowing. Dynamic Levels: With increasing challenges, the game keeps you engaged and on your toes. Satisfying Animations: Merging boxes, filling docks, and chain reactions deliver rewarding feedback. Simple to Play, Hard to Master: Easy tap controls make it accessible, while the growing complexity ensures hours of fun. Can you master the conveyor chaos and become the ultimate stacker?
