🌊 tide-games

games that share one sea

💬 the common room — fleet chat on nostr, signed with your own key

One secp256k1 key is a nostr identity, a Bitcoin address, and a signer — and your balance is a signed trail any game can verify, not a number in anyone's database. Every game here is pure static, every pixel from code, and where chance sails, the next Bitcoin block decides — nobody knows the outcome before the tide comes in, and anyone can check it after. The pattern is documented in BUILDING-GAMES.md — build a boat and join the fleet.

Setting sail

A ♠ K ♥ the champion waits in the back room

♠️The Den ⚓ seal-ready player-attested

The Tavern's back room: heads-up limit hold'em for gold against the Libre Poker champion — 296 million hands of training across the felt. Stacks carry, you play to the felt, winner takes all. The one fleet game that is honest about its trust: your result is attested by your signature, not proven by a block — the till caps what that trust can cost.

a million shares, and the tide keeps none of them

🏛️The Season DAO ⚓ seal-ready one-way

A million shares a season, one gold each, bought with sealed gold that is burned on the spot. The book lives beside Tideholm's hall of fame and outlives the season: who holds it is drawn live, the sale and the holders as charts. No vote and no trading yet — each is a later law.

Tide Dice — stake on a roll seeded by the next block, verify every round offline, and walk your winnings home on a signed slip. The venue that proved the courier pattern.

Tideholm — an island empire seen from above

🏝️Tideholm the home port

The island empire the gold comes from — a slow-burn browser strategy game in the classic early-2000s style. Raise your banner, seal your gold at the Tidegate, and sail it into the fleet.

Brine the crab beside a rockpool with a gold coin glowing in one hollow

🦀Rockpool honest urn

Dig for wreck-relics with Brine the crab. The pool is an honest urn — the odds shift with every stone, completed relics pay on the spot, and knowing when to wade out is the whole game. Solved by the maths, charmed by the crab.

Five harbour masts flying signal flags, one being read with a 33% odds badge and a fallen clue on the quay

🚩The Signal provably fair

Read the harbourmaster's hidden five-flag hoist — a deduction game where the order doesn't exist until you probe it. Wrong flags fall to the deck as clues, right ones lock and pay; sharp play faces exactly 3%, and every probe verifies.

A blackjack table with an ace and jack of hearts beside the dealer's up card

🃏The Jack provably fair

Six-deck blackjack at the jackstaff — dealer stands on 17, naturals pay 3:2, double and split as the book allows. The strategy book itself is derived from first principles in the tests, and every finished hand replays from its seed.

Pocket aces on a poker table beside the title The Wardroom - tournament poker in the officers' mess
