Rune Board Battler
Roguelike card-flip battler
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
◆ Place. Capture. Chain.
Play cards onto a 4x4 board — if your attack beats the enemy's defense, you capture (flip) their card. From a captured tile, captures ripple onward to the next; the longer the chain, the more of the board flips in a single move. That satisfying chain reaction is the heart of the game.
◆ Four heroes, four very different games
- Venom Witch: melt high defense with Poison, then capture in an avalanche
- Chain Dancer: keep chain-captures flowing to seize the board at once
- Swarm Queen: bait captures to flood the board, then crush with spawning minions
- Wall Maiden: hold firm, then punch through with Pierce
Passives and signature skills change how each hero plays completely.
◆ Relics — build your own way
Relics you collect along the way define your strategy: raise chain rates, grant Pierce to Walls, boost specific tags, and more. Combine freely, including greedy, high-risk "quirky" relics.
◆ A 3-act branching map
Battles, elites, bosses, shops, rests, treasures, and events. Your route is your strategy. Bosses bring act-specific terrain and gatekeeper gimmicks.
◆ The real game begins after you clear it
Reach the top with a hero to unlock "Ascension" — higher difficulties where enemies grow stronger, plus new units unlocked on your first clear. There is also a fixed-seed "Daily Challenge." And beyond it all lies the "Abyss," a final gauntlet against the True Demon Lord.
◆ Snappy and offline
A battle takes a few minutes. Suspend and resume runs anytime. Play with no internet connection. Turbo playback and prediction hints (toggle off once you are used to it) are included.
Now — capture, get captured, and chain!
