- This Regrowth Incremental progression guide walks through all six stages from Energy extraction to the final island.
- Energy is king early: funnel perk points into Energy upgrades before anything else.
- Stage resets unlock new mechanics (Life, Fossils, Mining, Dungeons) and rarely wipe full progress.
- Prestige around 200 UDE and invest points into Cash multipliers first.
- Cash is the biggest bottleneck in mid-game—boost it through the factory multiplier board.
Stage 1: Energy, Machines, and the First Reset
Stage 1 teaches the core loop: buy Tycoon buttons, complete the tutorial for 25 eternal shards, and start generating Energy from your machines. Your first priority is buying extractors—Basic, then Fast, then Heavy, then Super—each one multiplying your income dramatically.
Video Highlights:
- Machine upgrades and furnaces stack Energy bonuses quickly
- The crystal system unlocks after the Heavy Extractor (1 crystal per 10 seconds at base)
- First stage reset requires 200 trillion Energy and 250 jewels
- Resetting unlocks Life creation, cells, research, terraform, and monsters
The perk tree is where Stage 1 strategy lives. The video walkthrough confirms the winning approach: dump points into the Energy branch first, since nearly every later system converts Energy into other currencies. Crystals become your second focus—upgrade crystal worth (each crystal worth 2x, then higher tiers) and claim them automatically once automation unlocks.
| Upgrade Path | Priority | Why It Matters |
|---|---|---|
| Energy upgrades | ★★★★★ | Feeds every other currency conversion |
| Crystal value/tier | ★★★★☆ | Jewels fund the Stage 1 reset (250 needed) |
| XP gain | ★★★☆☆ | More perk points for the tree |
| Machine count | ★★★★☆ | Second machine at 4,000 Energy pays off fast |
Press the M button to upgrade as much as possible in one click, and use the speed-up button on crystal timers. An auto clicker makes crystal tier upgrades nearly instant.
Stage 2: Life, Fossils, and Automation
Stage 2 unlocks Life creation—cells, logs, research, terraform, and monsters. Life shards become a secondary loop: generate them, spend them on fossils, then reset fossils for permanent multipliers.
Unlock Life Creation
Hit the Life area requirements (750 trillion Energy to open), then create your first life currency and let it auto-generate through tiers.
Build the Second Floor
Unlock gears and the wrench. Upgrade the wrench repeatedly—gears fund your automation unlocks.
Buy Automation
Auto-buy frames and auto-buy upgrades cost gears. Prioritize these before pushing Life shard tiers.
Reset for Fossils
Reset life shards (about 1 billion life points gives 1.8k fossils) and spend on "more fossils next time" upgrades first.
Unlock Sap
Tree cutting and sap resets (5 million sap needed) push you into Stage 3.
Key Stage 2 upgrade: fossils boost life shards. The walkthrough spent most fossil income on this single node, and it paid off across every subsequent reset.
Your first sap reset consumes all stored logs. Bank extra wood upgrades before pulling the trigger, and use sap tokens in the sapling perk tree afterward.
Stage 3: Prestige, Cash, and the Upgrade Tree
Stage 3 unlocks the money tree, prestige, gold bars, emerald coins, and energy shards. This is where Cash becomes the bottleneck—it generates slowly and everything wants it.
Prestige Loop
- Resets machines and level only
- First prestige at ~200 UDE yields ~320 points
- Buy Starter Kit (5x Energy, 10x XP) first
Factory Multipliers
- Split points: Energy 32x, Cash 8x, others 2x
- Cash multipliers are the top priority node
Gold to Emerald
- Convert cash into gold, gold + cash into emerald
- 100 gold bars opens the next room (3x cash boost)
Runes open up here too—spend Energy (later research and life gems) on rune pulls for Energy, crystal, platinum, and damage buffs. The walkthrough recommends waiting until prestige 5 before mass-opening runes, since cash upgrades accelerate rune acquisition dramatically.
Grab the passive prestige point upgrade early in Stage 3. It keeps prestige income flowing while you AFK, removing the need to babysit resets.
Stages 4-5: Crystal Barn, Bonds, and Mining
Stage 4 unlocks the crystal barn—barn tiers reset crystal and factory progress (keep the tier itself), and higher tiers introduce opals, quartz merging, and eventually blue steel. The quartz merge mini-game is genuinely fun: crystals spawn on a board, merge them, then reset merge progress to bank blue steel toward Stage 5.
| System | What Resets | Target |
|---|---|---|
| Barn tiers | Crystals + factory | 5M opal per tier |
| Opal loop | Crystals, jewels, barn contents | Tier 4-5 unlocks |
| Bond tiers | Adamantium progress | Bond 7 for next stage |
| Terraform | Life gems | Extra boosts, roots, monster evolutions |
Stage 5 unlocks mining, the forge, ores, and mastery. The loop:
- Mine stone, gemstones, coal, and tin; buy path upgrades with stone
- Craft pickaxes at the forge—quality and damage scale with materials
- Upgrade the forge itself for bonus damage (locked recipes open this way)
- Depth milestones matter: dirt, mud, basalt—deeper layers unlock rarer ores
- Mining levels grant XP, damage, and ore multipliers—dump perk points into ores first
The pickaxe jump is enormous: from 200 damage to 16 million, then billions, as iron-gated recipes unlock. Cash upgrades from Stage 3 are the main driver of pickaxe damage, so keep that prestige loop running.
Stage 5's exit requires roughly 1-5 million uranium found at basalt/blackstone depth. Only mine at your deepest sustainable layer—shallower floors waste damage scaling.
Final Push and Daily Routine
The last stage (Stage 6, Age 6) unlocks a brand-new island and dungeons. The full grind takes roughly 24+ hours of playtime spread across sessions—often close to a week casually. A stable endgame routine:
| Task | Frequency | Reward |
|---|---|---|
| Prestige reset | Every 200+ UDE | Points for cash/Energy nodes |
| Fossil + sap resets | When capped | Permanent life/wood multipliers |
| Rune pulls | After prestige 5 | Energy, damage, crystal buffs |
| Terraform + monster feed | When life gems allow | Roots, evolutions, dark crystals |
| Mining session | Main AFK activity | Uranium for the final stage |
Progression Milestones:
- Complete Stage 1 reset (200T Energy, 250 jewels)
- Unlock full automation (auto-buy frames and upgrades)
- Reach 5 million sap for Stage 3
- Hit Bond 7 and bank 500 blue steel
- Craft a 1B+ damage pickaxe at the forge
- Collect uranium and unlock Stage 6
Monster feed, roots, and frost all hide behind main progression but unlock serious multipliers. The walkthrough reached max monster evolution in seconds once fed—far better value than it looks.
FAQ
Q: What should I upgrade first in Regrowth Incremental?
Put everything into Energy on the perk tree. Energy feeds crystals, jewels, and every later conversion, so it compounds faster than spreading points across branches.
Q: Does the first stage reset delete my progress?
The Stage 1 reset requires 200 trillion Energy and 250 jewels. A no-reset option exists but costs extra—standard resets preserve most permanent systems while unlocking Life, cells, research, terraform, and monsters.
Q: When should I prestige?
Prestige first around 200 UDE for roughly 320 points, then repeatedly as you pass the threshold. Buy Starter Kit, prestige point gain, and Cash multipliers in that order.
Q: How do I get uranium faster?
Mine at your deepest layer (basalt/blackstone depth), keep upgrading pickaxes at the forge, and stack cash and rune damage multipliers. Depth milestones unlock better ore tables as you descend.
