How it works: XP, badges and boosts
Every game and every birth helps you grow: you level up, unlock badges and earn one-time boosts to push your strains further. It works as a guest too; when you first sign in, everything moves to your account.
1 · XP AND LEVELS
Every game fills the test tube
- Games: your score divided by 60 (a good game is worth 40–60 XP).
- Births: 10 XP for every virus born in the lab.
- Daily missions: 25 XP for each one completed (with an account).
- Badges: 25, 50, 150 or 500 XP depending on the tier.
There are 40 levels and each one asks a little more than the last: playing every day you reach about level 7 in a week, 14 in a month and 25 in three months; level 40 is for those who hold out for around eight months. Your title changes every five levels:
1–5 Patient zero
6–10 Carrier
11–15 Outbreak
16–20 Epidemic
21–25 Pandemic
26–30 Scourge
31–35 Plague
36–40 Extinction
2 · BADGES
Forty milestones in six groups
Badges mark your feats: infection, stars, map, vaccine and countermeasures, lab, collection. Each one has a tier that shows how hard it is: bronze comes early, silver takes consistency, gold is for the few, and there is only one legendary.
- EpidemicInfect 25% of the world in one game.Bronze
- Week on fireEarn at least one star in 7 daily challenges in a row.Silver
- LegendGet a legendary card.Gold
- ExtinctionInfect the whole world (99.5% or more): you need a legendary card and the right mix of boosts.Legendary

3 · BOOSTS
One-time boosts for free games
Before a free game you can fit boosts from your inventory to your card. They are used up when the game starts, even if it goes badly. The card's rarity decides how many it can carry: common 1, uncommon 2, rare 3, legendary 4, one of each type. They can't be used in the daily challenge, which stays the same for everyone.

4 · REWARDS
Boosts, card backs and titles
- Levels: a level I boost every two levels, a level II boost at levels 5, 10, 15, 25 and 35, a level III boost at levels 20, 30 and 40.
- Badges: every gold badge gives a level I boost, the legendary badge a level III one.
- Card backs: a new one at levels 10, 20, 30 and 40; pick it in your profile. Legendary cards keep their own.
5 · THE 100%
Infecting the whole world
Without boosts no game reaches 100%: the vaccine starts early, flights stop after the global alert and countries reached late don't have time to fill up. Even a perfect player stalls at around 65%.
100% (99.5% rounded up) only becomes possible with a legendary card and four level III boosts in the right combination, the right patient zero and near-perfect choices at the pauses. With three level III boosts you stop just short. It is the legendary “Extinction” badge: for very few.
