iPhone

Grow a glowing fungal spire and hold back the Blight. Research while you sleep, collect 24 Mycelial Cards, call down Rites and Rebloom into a 24-talent tree. In a pitch-black fungal hollow, one living spire is the only light left. You are the Sporewright, its keeper. The Blight crawls in from the dark: rot beetles, mold crawlers, spitters, burrowers, wraiths and hulking bosses. Your spire aims and fires glowing spores by itself. Your job is to decide what it grows into. GROW YOUR SPIRE Kills drop Nectar. Spend it mid-run on 22 upgrades in three trees: THORN for attack, BARK for defense, ROOT for income and utility. Every purchase changes the spire you can see, from a sprout to a crowned world-tree. HOLD BACK THE BLIGHT Waves escalate without end and a boss arrives every ten. Fifteen kinds of Blight, three of them bosses: the Rot Colossus, the Blight Matriarch and the Hollow Sovereign. Every run ends by design, and the Spores you gather make the next one stronger in the Mycelium Workshop. DIG THROUGH 8 TIERS Reach wave milestones to open deeper tiers, from Leaf Litter down to The Rotheart Maw. Each one brings tougher Blight, bigger payouts and a new look for the hollow. THE LONG GAME Past the Workshop, six long-term systems open one by one as you play: - Sporeries: 19 research lines on a real clock that keep working while the app is closed - Mycelial Cards: 24 cards to collect and level, from pods you open with Luminite earned in play - Mycelial Rites: 6 ultimate abilities you call down mid-run, with auto-cast - Quests and achievements, plus a 100-rank Sporewright Rank - Rebloom: reset for Mycorrhiza and spend it in a 24-talent tree - 6 spire skins to earn On our pacing simulator, a player who checks in four times a day first Reblooms after 10-13 hours of play, and reaching the seventh tier takes more than 150 hours. IDLE, YOUR WAY After five minutes away, your mycelium harvests Spores for up to 8 hours (up to 16 with research). Runs save at the end of every wave, so you can pick up where you left off. Play at 1x and 2x from the start, and up to 6x as you go deeper. BUILT FOR ONE HAND Portrait play, no aiming, big tap targets, and a moody, glowing 3D diorama. ADS AND PURCHASES Sporewright is free to play. There are no banner or pop-up ads. Rewarded ads are optional: a button tells you the reward before you watch (a doubled offline harvest, a free Spore Pod, 30 minutes off a research timer, or a second chance when your spire falls), with a small daily limit. The one-time Ad-free Pass in-app purchase gives you the same rewards without the videos, within the same daily limits. Nothing else is sold: Luminite, cards and pods are earned only by playing. No account needed. Your progress is saved on your device.
