Game rules
Packs
One free pack every 10 minutes, up to 5 in stock. When the stock is full, the timer stops: come back regularly so you don't miss any. Each pack contains 5 cards, the last one being at least a Village. Pro and Pro MAX subscribers get a bigger stock, a faster refill and a 15-card Pro pack every day.
Rarities
The collection is permanent: once you get a card, you keep it forever. A card's tier depends on the number of inhabitants of the locality, from Hamlet to Megalopolis. Where no census exists, the population is an estimate.
| Rarity | Inhabitants | Chance per card | Discard |
|---|---|---|---|
| Hamlet | 1 to 200 | 59.1% | 1 |
| Village | 200 to 2k | 26.8% | 5 |
| Town | 2k to 20k | 10% | 10 |
| City | 20k to 200k | 3% | 15 |
| Metropolis | 200k to 2M | 1% | 20 |
| Megalopolis | 2M and up | 0.1% | 25 |
Special cards
At most one special card per pack. Odds for a standard 5-card pack; they are doubled in a Premium Pack, multiplied by 6 in an Ultra Pack and by 3 in an Event pack, and a 15-card pack counts as three. Cards you haven't discovered yet stay hidden.
| Card | Chance per pack |
|---|---|
| City ??? | 1 pack in 400 |
| Metropolis ??? | 1 pack in 700 |
| Megalopolis ??? | 1 pack in 1,300 |
| City ??? | 1 pack in 2,500 |
| Metropolis ??? | 1 pack in 4,800 |
| Megalopolis ??? | 1 pack in 9,000 |
| City ??? | 1 pack in 17,000 |
| Metropolis ??? | 1 pack in 32,000 |
| Megalopolis ??? | 1 pack in 60,000 |
Trophies
Trophies can drop from any pack (except trial packs), with the same odds everywhere, as many times as luck allows. They are kept apart from the collection and their reward is added right away. Already subscribed: your next payment is pushed back one month (and a Pro who pulls a Ruby gets Pro MAX that month); gifted subscription: extended by one month; lifetime subscription: coins instead.
| Trophy | Chance per pack | Reward |
|---|---|---|
| Silver | 1 pack in 100,000 | 5 Holo Packs |
| Gold | 1 pack in 1,000,000 | 5 Full Art Packs |
| Diamond | 1 pack in 10,000,000 | 1 month of Pro |
| Ruby | 1 pack in 100,000,000 | 1 month of Pro MAX |
Market
Automatic bidding: you enter the most you're willing to pay and the game bids for you, just enough to stay in the lead, in 5% steps. Your maximum stays secret and is held from your coins while you lead; if someone outbids you, you get it back right away, and if you win you only pay the price reached. Example, a card starting at 100 coins: Alice sets 500 and leads at 100; Bob sets 300, Alice leads at 315; Chloé sets 1,000, takes the lead at 525 and Alice gets her 500 coins back. A bid in the last 2 minutes extends the auction by 2 minutes, so nobody wins by swooping in at the last second. Listing is free; the seller pays a 5% fee only if the card sells. Average price, cheapest offer and price history of a card are for subscribers.
Seasons and teams
Every month, a season ranks players and teams. A completed daily quest earns 10 points, a weekly quest 40 and the daily reward 5. A player's points also count for their team, which has 10 members at most. The top 3 of each ranking win Premium packs and coins; the top 3 of the solo ranking also win a unique profile background, marked with their rank and the month of the season. The team extension from the shop raises this limit to 20.
Fair play
Opening all your packs, discarding your duplicates and automatic bidding are built into the game: no external tool is needed. Scripts and extensions that play for you are forbidden. Nonstop activity or consistently instant reactions are flagged and can lead to account suspension.
