How it works

Lethal Card

• Your player card: name, ELO, rank, wins and losses, best streak and your last 10 games. It starts counting on its own from your first game against a person — even as a guest.
• Save the card as an image and post it, for example on Reddit. The code on the image leads to a verification page where anyone can see the numbers are real.
• Pick an artwork for your card — next to the card or softly in the background. The same picture becomes your avatar in games, with friends, on trophies and on the leaderboard.
• Change your nickname any time with “Change nickname” in Lethal Card or on your trophies. With a saved profile your name is the same on every device.

ELO & ranks

Saving your profile

• Friends and trophies need a lasting profile. You save it with a passkey — Face ID, fingerprint or your device lock. No password, no email.
• When saving, you choose a unique name. Friends find you by it and it is part of your trophies link.
• On another device, sign in with the same passkey and your card, friends and trophies are there.

Friends & chat

• Add a friend by their name, or after a game with the Add button under your opponent’s name.
• The chat shows who is online and who is typing. Challenge a friend to a game with one tap.
• Once a challenge is played, the chat shows the result with a link.
• Tap anyone’s name or avatar — on the leaderboard, on trophies or in chat — to open their player card.
• In the chat menu (⋯) you can remove, report or block a friend.

Trophies

• Your trophies page shows everyone you have beaten — how many times, in which games, with replays of each game.
• Share your trophies link; its preview shows your rank, ELO and record.
• You can also delete your profile there.

Notifications

• When a friend messages you, challenges you or someone sends a friend request, you see a heads-up on any page and a count next to Friends.
• Turn on notifications for when the site is closed in Friends. On iPhone, first add the site to your Home Screen (Share → Add to Home Screen) and open it from there.
• You can turn them off any time in the same place.

Verified results

• Every finished online game has a result page: who won, the score, the list of games and a replay of each.
• The server records the result, not a player’s browser — it cannot be edited.
• At the end of a game, send the result link or the result image to your opponent or your group.

Battleship Extreme

• Question marks appear on your opponent’s sea. Hit one and you get a weapon: a nuke, a mini nuke, a scatter shot, a torpedo or a radar.
• Pick the weapon below the board, then a single tap on the target fires it — on phones too.
• Where a scatter shot lands is decided by the server only when you fire, and the cells appear one by one as the shots land. Nobody can work it out in advance.
• Radar shows how many unhit ship cells are in a 3×3 square. Your opponent sees where you sent it, and you see theirs.

Safety & reporting

• Report a player in a game with the Report button, or a friend from the chat menu. Moderators review every report.
• A blocked player cannot message you or send you requests.
• What we store about you and why is described in the Privacy Policy.
