A four-digit code is locked in the vault. Every guess comes back with clues: how many digits are right and in the right place, and how many are right but in the wrong place. Work it out, open the vault, and take the pot.
PLAY LIVE
Duel is you against one other player. First to crack the code wins. When few players are online, some opponents are computer-controlled; tables of 50,000 and up are people only.
• Race — same code, first to crack it wins.
• Setter — build a code, break theirs.
• Blitz — how many can you open in 75 seconds?
Arcade puts four players at one table.
• No Limits — any digit, any number of times.
• Blind — your clues fade. Remember them.
• Wild — six digits, repeats allowed.
More formats open up as you level up.
THE DAILY VAULT
One code for everyone in the world, every day. It's free, your first run is the one that counts, and you can see how you did against your friends, your country and the world.
STAKE COINS, WIN THE POT
Pick a table, from the Back Room at 50 coins up to The Reserve at 100,000. Everyone at the table puts in the same stake. In a Duel the winner takes the pot; in Arcade, first place takes three stakes and second gets theirs back. Nothing is kept by the house. The bigger your balance, the bigger the table you can sit at.
FRIENDS AND RANKINGS
Find friends by name or Player ID, see who's online, and play them in a private room. Then see where you stand on today's, this week's and the all-time boards.
MADE TO FEEL GOOD
Mechanical key clicks, clues that lock into place, and a real vault door swinging open when you get it.
FOR EVERYONE
Every clue has a shape as well as a colour, so colour is never the only signal. VoiceOver, larger text, Increase Contrast and Reduce Motion are all supported.
COINS ARE WON, NEVER BOUGHT
Coins come from playing: matches, the Daily Vault, or an optional short ad. They are what you stake at the tables and what the Richest board counts, so nobody can buy their way up it. They are not money: they can't be cashed out or sent to another player. If you ever run out, the game gives you more for free.
DIAMONDS DRESS YOUR VAULT
Everyday vault finishes, keypads, treasure and security go on sale for coins as you reach their level. The gold, the gems and the top vaults take diamonds. Diamonds buy looks and nothing else: never coins, seats or anything that helps you win. Every level you reach pays 10 diamonds for free, and the levels you already have count.
