Read full description

Grimspire is a gothic slot machine roguelike where every spin is a battle for survival. Step into a cursed dungeon where combat plays out on dark, ornate slot reels. Match skulls to deal damage, potions to heal, shields to block, and gold to grow your hoard. But beware the curse symbols that turn your own reels against you. GOTHIC SLOT COMBAT Spin a 3x3 reel with 12 unique symbols per floor. 8 paylines across rows, columns, and diagonals. Hold reels and re-spin for strategic depth. Chain consecutive hits for devastating combo multipliers. 5 STARTING GRIMSPIRES Blood, Fortune, Iron, Chaos, or Shadows. Each grimspire transforms your starting reel and playstyle with unique risks and rewards. FORGE YOUR REEL Add or purge symbols between floors. Thin your reel for consistency or stack damage types for devastating combos. 20 DARK RELICS Passive modifiers across 3 tiers. Vampiric healing, curse immunity, critical strikes, gold multipliers. Stack them for unstoppable builds. 5 EVENT ROOMS Fate's Gambit, Dark Duel, Dark Memory, Dark Vault, Dark Solitaire. Card-based mini-games that break up combat with risk and reward. 5 ASCENDING STAKES White through Blood. Each stake stacks brutal modifiers. No heals, double damage, heavy curses. The ultimate challenge awaits. DAILY CHALLENGES Seeded daily runs. Same dungeon for every player. Build streaks, climb leaderboards, unlock rewards. NO ADS. NO SUBSCRIPTIONS. Free to play with optional one-time Grimspire Pro purchase for unlimited runs, all cosmetic themes, and full run history. PRIVACY FIRST Zero data collection. No analytics, no tracking, no ads.

On price, in-app purchases and device support there is nothing between them.
