Wall Reaction - Chain Game

Drop an orb, or build a wall. Every turn, you choose. Wall Reaction is a tactical chain reaction board game that blends explosive cascades with clever defensive strategy. Push a cell past its critical mass and it bursts into neighbouring tiles, capturing them and triggering chain reactions until the entire board turns your colour. Defend against your opponents with tactical walls. A wall absorbs the blast and cracks, breaking on its final hit. Every chain reaction you plan must navigate around—or blast straight through—enemy defences! 💥 HOW TO PLAY • On your turn, add an orb to an empty cell or one you own, or spend a wall to block an edge. • Critical mass: A cell bursts when orbs match its neighbours (2 in corners, 3 on edges, 4 in the middle). • Explosive reactions: Each burst throws orbs to neighbouring cells and converts them to your colour. • Tactical walls: Walls absorb blast impacts and crack with each hit. • Fair path rule: Every cell must keep at least one open side—no trapping or sealing off the board! • Last player standing wins the board game match. • Complete the interactive guided tutorial to learn in under two minutes. 🎮 GAME MODES & MULTIPLAYER • Pass and Play: Offline multiplayer for 2 to 8 players on a single phone. • Local Wi-Fi Multiplayer: Host a local room and battle friends on your Wi-Fi network without internet. • Versus AI: Five smart AI bot personalities, from gentle Pebble to grandmaster Fortress. • Custom Board Sizes: Play fast 6×6 casual matches or sprawling 15×15 tactical wars. • Board modifiers: Custom wall health, wall regeneration turns, and symmetric pre-built Fortress layouts. 🧩 DAILY PUZZLES & BRAIN CHALLENGES • 60 Handcrafted Strategy Puzzles across 6 chapters with 180 stars to earn. • Daily Challenge: A fresh chain reaction logic puzzle every single day with streak rewards. 🎨 CUSTOMIZATION & REWARDS • Unlock 6 minimalist visual themes, orb styles, wall designs, player titles, and 32 custom avatars. • Eye-friendly soft Dusk dark mode for evening play. 🛠️ STRATEGIC TOOLS • Long-press preview: Hold any cell to preview the chain reaction before you place your move. • Smart AI hints and turn undo powered by in-game Sparks. • Match replays, lifetime stats, and achievement tracking.
