Voidle is an idle RPG with a 1090-node skill tree, a prestige loop that scales past the visible cap, and gear you can corrupt for explosive trade-offs. Combat runs by itself. You fight 100 enemies per depth, then a boss, then move on. Every 100 depths a milestone boss drops an artifact that survives prestige. Damage scales past Decillion and keeps going. MONETIZATION No ads. No energy. No premium currency. No timers. One optional $1.99 IAP removes the rewarded-ad gate on the offline-rewards popup. That is the entire store. CLASSES Warden tanks everything you throw at it. Stalker crits hard and dies fast. Occultist rots enemies from inside with poison and burn stacks. Revenant drinks the blood of what it kills. Your class sets your starting position on the skill graph; you spend skill points to path outward, node by node. You can never fill the whole graph, so the route you take shapes the build. PRESTIGE Reset your run for permanent skill points based on the new ground you covered. Roughly 500 SP fills the tree out. Past that, every overflow point boosts HP, Attack, and Defense up to +2000% (caps at 2000 overflow). Lock Spec on prestige keeps your build; off lets you fully respec and switch class. FORGE Where builds get specific. Enchanting adds a stat to gear or a brewed potion. Corruption pushes one stat much higher at the cost of another: +50 to +120% Attack for -15 to -25% HP, +80 to +150% Defense for -15 to -25% Speed, that kind of trade. Brewing crafts potions with adjustable power (1 to 5) and duration (30 seconds to one hour). Enchanting a Power 5 brew bumps it to Power 6, the only way to reach that tier. GEAR 27 base equipment slots: weapon, five armor pieces (head, chest, legs, boots, gloves), necklace, ten finger rings, and ten toe rings. Mutation nodes on the skill graph unlock another 30 slots. Five rarity tiers from Common to Legendary, with stat values scaling exponentially by depth, so a Legendary at depth 50 dwarfs one at depth 1. OFFLINE PROGRESSION The game keeps fighting while the app is closed. Come back to a summary of what happened: Ichor at half rate, drops capped by inventory space, milestone bosses defeated if you can clear them. Active buffs run down during offline time, so a one-hour potion before an eight-hour break does what you'd expect. OTHER THINGS WORTH MENTIONING * Market refreshes every five depths, with reroll, pin, and slot-request options * Auto-equip, auto-salvage, and auto-sell handle drops at scale * 11 essence types target specific enchants or corruption rolls * Live graphs for kills per minute, depth progression, and Ichor income * Soft and hard caps on Speed and Crit, so stat stacking has diminishing returns somewhere This plays fine one-handed on a phone. It also rewards a lot of time staring at the skill graph. Both are intended.

Universe Exploration holds the better App Store score, 4.4 against 4.1. Both are backed by a comparable volume of ratings — 9 and 14 respectively.
