The rules between you and us.

The game

Free

Krystal Wars is free: no price, no subscription, no ads. Without an account you can play against the AI and on one screen. An account adds online battles, friends, messages, your decks on every device, and the shop. Accounts are for players aged 15 or more.

Credits and cards

For playing, never for money

• CreditsThe game's points. They buy boosters and bundles in the shop, and forge the cards you lack. For now they come from your first faction's welcome gift, from copies past what a deck can hold, and from us. No money buys them.
• BoostersEach booster holds cards of one faction, drawn by our server as you open it. The shop shows the odds.
• CardsYours to build decks with, kept on your account.

None of them has any value in money: they cannot be bought, sold or exchanged for money, in the game or outside it, nor passed to another account. To keep the game balanced, cards, prices, odds and the shop can change, and a card can be changed or taken out of play. They go with your account, and end with the game if it ever stops.

Fair play

Play fair, stay kind

• No cheatingDo not change the game, its code or what it sends to our server, and do not use a bug to win. Found one? Tell us.
• No botsPlay your own battles. No program plays them for you.
• No abuseNo harassment, hate, sexual content or spam, in names or in messages.

Any player can block or report you. A block keeps you apart: no friend request, message or challenge between you. Reports reach us with the recent messages they are about. Break these rules and we may suspend your account: no more online battles, friends, messages, synced decks or shop. Write to crystalwars@boiret.com and we tell you why; you can contest it there too.

Our part

A game that changes

We keep working on the game: rules, cards, prices and features change, and it may stop one day. We do our best to keep it running, but it can be down or have bugs, and a battle under way can be lost. We answer for what French law makes us answer for. We do not answer for what other players do, or for what is beyond our control.

Your account

Leave whenever you like

Delete your account at any time: in the game, open your Profile, then Delete account. Your cards, boosters and Credits go with it, for good. What else goes and what stays is on our privacy page.

Law

French law

These terms follow French law. If something goes wrong, write to us first. If we cannot settle it together, it can go to the French courts, or to the courts where you live, and you keep every right the law of your own country gives you. When these terms change, we post the new version on this page at least 15 days before it applies. If you disagree, you can delete your account before then.
