Launch colorful UFOs and watch pixel art disappear, one satisfying cube at a time! Welcome to Spaceship Out, a relaxing color sort puzzle where every spaceship has a mission: collect matching cubes, fill up, and fly away. Each level features a vibrant pixel art picture built from colorful blocks. Your goal is to clear the entire picture by choosing the right UFOs in the right order. Tap a numbered UFO from the launch queue to send it into the docking bay. Blocks of the same color with a clear path fly toward your ship automatically. As cubes arrive, the number on the UFO counts down. When it reaches zero, the ship blasts off and frees a docking slot. Here's the challenge: only 5 docking slots are available. Think ahead, avoid filling every space, and keep the colors flowing!

About

Stack Popper

Features
Read full description

Stack Popper is a satisfying 3D puzzle game where every shot can change the shape of the world. Rotate the model, choose your shot, and hit colorful blocks that match your ball. Clear connected groups, trigger special effects, and carefully manage your limited shots to take down the entire structure. ROTATE TO FIND THE RIGHT ANGLE Slide to rotate the 3D structure and explore different sides of the level. Look for matching colors and find the best angle before taking your shot. MATCH COLORS TO POP BLOCKS Launch a ball at a block with the same color. When matching blocks are connected, clearing one can trigger a chain reaction and remove neighboring blocks of the same color. MAKE EVERY SHOT COUNT Each level gives you a limited number of balls. Choose your targets carefully and plan a path through the structure before you run out of shots. DISCOVER SPECIAL BLOCKS Different blocks create different opportunities. Some can clear an entire row or column, while others clear an area or target a color automatically. WORK AROUND OBSTACLES Cages and shields can block your progress and require you to think about which blocks to remove first. Look beyond the surface and plan your next move. WATCH THE STRUCTURE FALL As blocks are cleared, unsupported pieces can drop away from the structure, creating satisfying chain reactions and opening new areas to explore. CLEAR EVERY BLOCK Remove the entire voxel structure before your shots run out. Rotate, aim, match colors, and find the most efficient way to bring every level down.
