Climb a tower of dark fantasy โ€” even while you are away. Rune Tower is an idle RPG built on automatic battles, deep loot and jobs you can switch between freely. Your hero keeps growing offline; you come back, rebuild, and climb higher. BATTLES THAT PLAY THEMSELVES Both sides act as their action gauges fill. No input needed. What decides a fight is the equipment, runes and job you chose before it started. LOOT THAT GOES DEEPER THE MORE YOU DIG Three slots โ€” weapon, armour, ring โ€” across four rarities, 25 kinds of affix, and a quality score from 0 to 100. Two items with the same name are rarely the same item. Epic and Legendary gear carries a build effect. Critical, ailment, follow-up, counter, shield, healing, execution โ€” which of the eight you roll changes how you fight, not just how hard you hit. And Legendary gear can roll a Rule Breaker: one turns your defence into damage, another sends the health you recover straight back at the enemy. Each breaks a single rule the rest of the game plays by, and the moment one lands, your build jumps a tier. Reforging lets you pick the affix to reroll. You see the best roll it could produce before you commit, and after seeing the result you choose whether to keep the original. THIRTEEN JOBS, ALL YOURS Take a job to Lv100 and its trait carries over to every other job. The more jobs you finish, the stronger you are in all of them. EIGHTEEN RUNES Six slots decide how you fight. Grind enemies down with poison, chain follow-up hits, or turn their attacks back on them. THE TOWER KEEPS GOING 300 floors across Normal, Hard and Nightmare. Past them lie the Abyss, a descent that runs to depth 3000, and the Underworld, a second tower with its own equipment and relics. IDLE REWARDS Up to eight hours of rewards accrue while you are gone. The tower is climbed while you sleep. Hunt the gear, build your hero, and see how high you can get.

Scroll Dungeon

โ—† Healing, weapons, magic: they all turn to ash once used. Swords, armor, healing draughts, fire spells. In this world, every one of them is a single-use scroll. What do you bring? Where do you spend it? What do you hold back? In Scroll Dungeon, the hard choices start before you enter the mine, when you pack your pouch. โ—† Spend it, or save it? Burn a strong scroll and your pouch gets lighter. Save it and fall in battle, and every scroll you carried is lost with you. Use it, or hold it. That one decision can decide the run. โ—† Turn-based grid crawling Move one tile, and the enemy moves one tile. Nothing rushes you. Read the board and take the best line. Steam-driven machine horrors, sleeping sentries, reinforcements drawn by noise. Fight through, slip around, or burn a scroll โ€” every decision costs you something you cannot get back mid-run. Tap the board once to see your route and start walking. โ—† Clear it, or lose it all Clear a mine and you hold on to the scrolls you picked up along the way, plus the rewards. Fall in battle โ€” or retreat โ€” and every scroll you carried or found is lost. All that remains is the ash from the scrolls you spent. โ—† Failure compounds into power Spent scrolls become ash, which converts into permanent upgrades at the Ash Workshop. Those carry into every run. A lost run still makes the next one easier. Nothing you do is wasted. โ—† Mines that change with the day of the week The mine and its special rule are set by the day of the week. Monday doubles the enemies, Tuesday narrows your vision, Wednesday and Sunday make scrolls drop more often, Thursday locks your max HP, Friday doubles the ash you earn, and Saturday turns the enemies into a boss-grade gauntlet. Each day's first clear earns a reward. โ—† Nine classes Adventurer, Gear Rogue, Steam Swordsman, Scroll Mage, Steam Cleric, Steam Sniper, Overload Juggernaut, Alchemist, Karakuri Ninja. Each class fights differently. โ—† One run takes 5โ€“10 minutes It plays offline, and no account is required. โ—† What's inside - 50 scrolls (weapon / armor / healing / magic / accessory / material) - 27 enemies, including ranged, self-destructing, and summoning machine units - 8 mines, from a molten crater to a thunder spire, plus an endless one - 9 classes - 37 achievements, the weekday-based Daily Mine, and scroll synthesis โ—† About purchases The game shows ads and offers in-app purchases (Japan prices, tax included). - Gear Stone packs (small / medium / large): ยฅ160 / ยฅ480 / ยฅ960 - Remove Ads: ยฅ980 (one-time; banner ads disappear, and optional rewarded ads pay out without watching) - Adventurer's Kit: ยฅ320 (first purchase only; 200 Gear Stones + 2 pouch slots) - Monthly Pass: ยฅ240 per month (auto-renewing; 10 Gear Stones and 1 scroll daily) Gear Stones can also be earned in-game.
