Merge Galaxy is a calm, beautifully crafted merge puzzle set in the depths of space. Swipe to slide tiles across a 4×4 board. Match two of the same world to fuse them into the next one. Start with a single pebble, then watch it grow into a meteor, a moon, a planet, a sun, a pulsar, a nebula, and finally an entire galaxy cluster. FEATURES • Tactile swipe-to-merge gameplay you can master in seconds • 11 cosmic tiers, each with hand-tuned art and a short piece of lore • The Codex — your personal catalogue of the cosmos, unlocked as you climb • Auto-saved runs, so a quick game fits any moment • Best score and top tier tracking • Calm visuals with subtle glow and motion — no pressure, no timers • Light haptics and gentle sound design • One-tap Remove Ads option A short merge session feels great in line, on the train, or right before bed. Take your time, plan your swipes, and let the universe assemble itself one tile at a time. How far up the cosmic ladder can you climb?
