Your hero fights, levels up, and collects gear on their own. You just check in. Grindcrawl is a retro pixel-art idle hack-and-slash RPG. Dive floor by floor, chase Rare and Epic gear, and reincarnate to go even deeper. HANDS-OFF BATTLES • Your hero fights monsters automatically and earns EXP and gear. No tapping needed. • Your adventure keeps going while the app is closed. Collect your rewards the next time you open it (up to a time limit, which you can extend). • Assign level-up points by hand, or let them be assigned automatically at a ratio you choose. THREE HEROES AT ONCE • Keep adventuring to unlock a second and a third hero. All three adventure at the same time, even while the app is closed. • Reincarnation Points, Shards of Brilliance, and gear are shared. Levels and Attack, Defense, and Luck upgrades are per hero, so you choose who pushes deeper and who reincarnates. • Each piece of gear can be worn by only one hero at a time. DIVE DEEPER • Defeat five monsters to reach the next floor. Each new floor band brings tougher monsters and stronger gear. • Rare and Epic monsters are tough. With too little Defense, they may get away. • New areas open at floors 301 and 351, each with new monsters and new gear. GEAR THAT ROLLS ITS OWN STATS • Weapons, armor, and accessories come in three rarities: Normal, Rare, and Epic. • Every drop rolls its own stats, and higher rarities get more bonus slots. • Switch to Auto equip mode, and Rare and Epic gear stronger than what you have is equipped as soon as it drops. Or stay in Manual mode and choose for yourself. • Polish Epic gear with Shards of Brilliance to reroll its slots. Lock the slots you want to keep. • Equip two or more pieces of the same rarity (Rare or Epic) from the same floor band for an all-stat set bonus. COLLECT IT ALL • Defeat the same monster again and again to earn its Monster Medals, from Bronze to Platinum. Medals raise the chance of a gear drop when that monster appears as a Rare or Epic. • Donate gear to the Equipment Museum to fill its displays. Complete a Species Set for a big all-stat bonus. REINCARNATE AND GO FURTHER • The deeper you reach, the more Reincarnation Points you earn. • Spend them on permanent Attack, Defense, and Luck, more inventory slots, and a longer offline reward limit. Your gear, medals, and museum stay with you. • Each hero reincarnates on their own, and the points they earn are shared. CASINO MINI-GAMES • Play Slots and Poker in the Casino mini-games. • Coins build up over time, and you can also get them by watching ads. Exchange them for Reincarnation Points or Shards of Brilliance. MORE • Available in English and Japanese. • Plays on iPhone and iPad. • Get a notification when your offline rewards reach their limit. A few minutes here and there is all it takes. Check in, see how far your heroes got, and close the app.
