20480

Features
Read full description

20480 is a chain-reaction puzzle game that turns a simple idea into a deep, fast-paced strategic challenge. Slide tiles to merge matching numbers, trigger devastating combo chains, and fight off a relentless onslaught of enemy tiles โ€” all on a glowing neon board that never lets up. HOW TO PLAY Swipe in any direction to slide every tile on the board. When two tiles with the same number collide, they merge into a higher value. Consecutive merges trigger chain reactions that multiply your score. Keep chaining. Keep climbing. Reach 20480. POWER-UPS Build combos to earn game-changing power-ups โ€” then deploy them at exactly the right moment: - Row Clear: Obliterate an entire row in one shot - Freeze: Halt all enemy countdowns for 3 turns, buying precious time - Upgrade: Instantly promote any tile to the next tier - Shockwave: Detonate the center of the board in a 3x3 explosion FACE THE THREATS Three enemy tile types invade your board as the game escalates: - Bombs: They count down turn by turn. Defuse them with a Freeze or face the blast. - Ice: Freezes adjacent tiles, blocking merges and strangling your options. - Poison: Downgrades neighboring tiles one tier per turn, slowly eroding everything you've built. CAMPAIGN MODE Thirty levels across six worlds of escalating challenge. Early worlds introduce the mechanics on clean 4x4 grids. Later worlds layer in gravity shifts, cracked tiles, and black holes โ€” then flood the board with enemies on 5x5 and 6x6 grids. Every level has a target: hit a score threshold, reach a tile tier, trigger a chain reaction, or survive the onslaught. Earn up to three stars per level and push for perfection. ENDLESS MODE No move limits. No mercy. Chase the highest score you can reach before the board overwhelms you. An ascension system keeps escalating the challenge the longer you last โ€” stronger modifiers, higher stakes, no ceiling. DAILY CHALLENGE A fresh seeded puzzle every morning. Same board for everyone, one chance to top your personal best. FEATURES - 30 campaign levels across 6 worlds with distinct hazards and goal types - Endless survival and Daily Challenge modes - 10 power-ups earned through combo chains - 3 enemy tile types โ€” bombs, ice, and poison โ€” each with unique behavior - Dynamic board mutations: gravity shifts, cracked cells, black holes - Three grid sizes: 4x4, 5x5, and 6x6 - Neon cyberpunk visual style with fully procedural animations and effects - Swipe and touch controls built for one-handed mobile play - Local high score tracking across all modes Can you reach 20480?
