Six trees walk into the forest. One walks out. Make sure it is yours. Free to play. No ads. Six Hollows is a draft-and-watch autobattler: each round you pick one item, slot it into your tree, and the fight plays itself. No tapping, no timers, no filler. Your job is the plan. The joy is watching it work. A ROOM FULL OF GHOSTS This is async PvP at your pace. Every run seats you in a room of six; your five rivals are ghosts, builds recorded from other runs near your rank, replayed against you round by round exactly as they were drafted. No live matchmaking, no one rushing your turn, no penalty when life interrupts mid-run. Outbuild them, outlast them, and when a rival falls, their echo lingers for someone to duel. Then leave your own mark: every run you play leaves a ghost behind for other players to face. Make it something worth fearing. EIGHT WAYS TO RUIN A TREE Cinder burns. Blight poisons. Deadeye crits. Rend bleeds. Salvo fires again. Clockwork accelerates. Frostbite stops slots cold. Zap jumps the line. An arsenal across four rarities, every piece growing through three levels. Stack one family until it sings, or splice several into something the room has no answer for. EVERY RUN ITS OWN STORY Open with a Spirit that bends the whole run. Crown an item at max level and pick a boon that bends it further. If a fight drags, sudden death steps in and finishes it. Runs stay short, sharp, and one decision away from legendary. CLIMB THE FOREST Ranked from your first fight: six ranks, Sapling to Elder, and a fresh season on the first of every month. Plant your tree. The room is waiting. Six Hollows needs an internet connection to start a run; a run already in progress finishes fine offline.

SOULSTACK — a necromancer auto-battler of stacked souls. You were a master of death, stripped of power and cast into the Pit: an endless tower of the dead. But every foe you slay rises to serve you. Recruit them. Fuse them. Weave a legion that multiplies — and climb. ◆ A LEGION THAT COMPOUNDS Draft undead, beasts, mages, and rogues into your warband. The power isn't flat stats — it's synergy. Line up the right tribes, roles, and Authorities and your army doesn't add up, it MULTIPLIES. Find the engine, break the wall. ◆ CLIMB THE ENDLESS PIT Every run is a fresh draft. Scout the floor ahead, counter it, and climb — the dead grow without limit as you rise. Fall, and you return to Level 1… but the servants you raised carry into the next life. Rise again. ◆ COMPETE WITH FRIENDS — ON YOUR TIME Conquer the Pit and set your army to guard your star. Then raid your friends' stars across a season of standings. It's all ASYNC — no live matches, no waiting, no always-online. Take a turn whenever you like; the war continues without you. ◆ FAIR BY DESIGN Premium — buy once. No ads. No gacha. No pay-to-win: the unlock sells the full climb and the collection, never power. Competition is normalized, so skill wins, not spending. ◆ THEORYCRAFT-DEEP Deterministic combat and simulation-tuned balance reward mastery over luck. Dozens of units, items, and Authorities to combine — the deeper you read the synergies, the higher you climb. Raise the dead. Stack the souls. Climb.
