Become an Anime Billionaire Gems Guide

Gems are the premium soft currency behind the strongest permanent power spikes in Become an Anime Billionaire. Cash funds everyday rolls and rebirth thresholds; gems fund the merge machine, higher-quality rolls, and some crate / upgrade paths. Burning gems on the wrong thing early is one of the most common ways new players stall. This guide covers how gems are earned, what they should buy first, and how they connect to rebirth, lucky blocks, and totems.

How gems are earned

Exact rates change with updates, but players typically gather gems from:

Source	Reliability	Notes
Passive gem upgrades (rebirth tree)	High	Invest rebirth points into gems-per-minute style upgrades
Gameplay milestones / quests	Medium	Check in-game prompts after patches
Premium / Robux packs	Optional	Never required to progress with smart play
Event rewards	Seasonal	See the Events hub

Prioritize rebirth upgrades that generate gems over time once your cash multiplier is online. Passive gem income compounds across every future run.

Income progression and unit investment walkthrough

Best gem spends (priority order)

1. Merge machine fusions for Epic+ duplicates — Five copies into one upgraded earner. Full walkthrough: Merge Machine guide.
2. One targeted premium roll session after a patch — Only when the Tier List shows a new chase unit and your base is already full.
3. Selective crates — Prefer income / luck totems once merges are funded.
4. Cosmetic or low-impact spends — Last. Cosmetics do not raise cash/s.

Spend table

Goal	Spend gems?	Why
Fuse five Epics / Legendaries	Yes — top priority	Permanent income spike
Fuse Commons	No	Return on gems is too low
Premium rolls with empty slots	Maybe	Fill with code units / Friendship blocks first
Premium crates on day one	No	Starves merges
Panic rolling after a bad session	No	Wait for codes / events

Gems vs free rewards from codes

August 2026 codes hand out Super Lucky Blocks, Friendship Lucky Blocks, and Kiriko — none of those spend gems. Always redeem codes before opening the gem shop:

1. thisissecret → Kiriko
2. sorry → Super Lucky Blocks
3. tyfor10k / bonusgift → Friendship Lucky Blocks
4. Only then evaluate gem merges for duplicates you already hold

Synergy with rebirth

Rebirth resets cash and placed units but keeps permanent upgrades — including gem generation. Practical loop:

1. Earn cash → hit rebirth threshold (Rebirth guide).
2. Spend early rebirth points on cash multiplier + offline income.
3. Add gem generation once cash income feels stable.
4. Use the next run’s gems to fuse the best duplicates you re-acquire.

Never delay a healthy rebirth just to “spend every gem” if your income has already plateaued.

Mid-game gem checklist

• Base slots full (Base Building)
• Active codes redeemed
• Weakest slot identified via Tier List
• At least one Epic+ fusion candidate ready
• Gem balance covers that fusion with a small reserve left
• Totem / crate urge delayed until after the fusion

Common mistakes

1. Premium rolling before redeeming codes — Free units and blocks are gem-equivalent value.
2. Fusing everything — Commons drain gems that should upgrade Epics.
3. Ignoring passive gem upgrades — One rebirth node can fund dozens of future merges.
4. Spending gems right before rebirth without a plan — Fused units still reset on rebirth; time fusions for the run where you will use them longest, or accept the reset intentionally.
5. Buying every crate — Totems matter, but merges usually matter more.
