The house always wins. That's the point.
Your Coinkeep economy has quests that mint money and a market that moves it around - Highroller is where it goes to disappear. Twenty-two ways to bet, every one a block you place, every wager banked straight against the Coinkeep balance. Build a corner arcade or a full casino floor; your players will fund the carpet.
NEW IN 2.0.0: BE THE HOUSE. Place a Casino Cage, fund it from your own Coinkeep balance, and link your tables to it. Now the stakes your players lose flow into YOUR bankroll and the wins pay out of it - 24/7, whether or not you are logged in. Name the place. Set the odds inside the server's limits. Watch the take. (Server owners: it all sits behind allowPlayerCasinos, default OFF - never flip it and 2.0.0 plays exactly like 1.0.0.)
Every table publishes its real numbers before anyone bets: "The Lucky Creeper - pays 91.7%" right there on the screen. A stingy table is visibly stingy, the server's RTP floor kills the scams, and the number cannot move under you - a high-low climb or a sweeper board locks its rate the moment your stake goes in, and every pot locks its rake the moment it opens. You set the price; the server still rolls the dice. Every bet a cage accepts reserves its maximum payout first, so a player casino can go bust but can never owe money it doesn't hold.
The Cage dashboard is your control panel - bankroll, available, reserved and lifetime take on one page, your whole casino floor on the other. Every game in range, how far and which way, and one click to link it, unlink it, or steal it back off your other casino. Open the cage and your floor lights up gold; anything banking for the wrong bankroll lights up red.
Server owners: highroller-server.toml sets the master toggle, the RTP floor and ceiling, the max bankroll a cage may hold, who may operate one, the rake ceiling, and the house's cut of operator profit (default 10%, burned on withdrawal - your server keeps its money sink even with a hundred player casinos running).
Naming a casino is a moderation surface, and it is treated like one. No built-in wordlist - those refuse half the good casino names and stop none of the bad ones. You get the tools instead: an op can rename or wipe ANY casino's name (look at the cage, or at any table it banks), whoCanName restricts naming to ops or switches it off entirely, every rename is written to the server log with the player, their UUID, the cage's coordinates and the old and new name, and casinoNameBlocklist is there if you want one - it ships empty, with your terms, in your language.
THE FLOOR - Standing slot cabinets, two blocks of casino and a 400x server-announced jackpot with the reels at eye height. High-low climbs, the under/lucky/over dice table, a wheel you can read the odds straight off, and $500 scratch cards hiding a $100,000 ticket.
THE TABLES - Real blackjack: 3:2, dealer stands all 17s, double and split, a 0.57% edge if you play perfect basic strategy - the best game in the house, in writing. Jacks-or-Better video poker on a true 52-card deck with the six standard paytables. European roulette with timed rounds where the whole server bets the same spin. Punto banco baccarat with the genuine third-card tableau. Casino War with the double-tie bonus. Sic Bo on the Atlantic City paytable. A Creeper Sweeper where every safe tile multiplies the pot until the hiss. Keno with no pick-count trap and a 250,000x top prize.
THE SERVER ROLLS THE DICE - Every outcome is decided server-side. The client only animates what it's told - the dealer's hole card never even crosses the wire until the hand is over.
THE BOOK - A Server Lottery whose pot everyone can watch grow. A Bookmaker Stand where an operator opens a market on ANYTHING by handing it a written book - players stake, winners split the pool parimutuel-style, and the bookie can't bet his own book. Duel Wagers where two stakes go on the pedestal and the next death settles it. A Race Kit - starting gates that physically hold the pigs until the gun, a checkered finish line that pays the winning backers the moment the first rider crosses. Bingo Night, one card each, first line takes the pot. Plinko with three published boards up to 850x. And bolt a Progressive Jackpot Link onto your slots: one server-wide pool, fed by every linked spin, until triple Stars takes the LOT.
PLAYER-VS-PLAYER MONEY IS RAKED, NEVER EDGED - lottery, book, duels, races and bingo take a flat configurable cut (5-10% defaults) and the rest goes back to players. If nobody backed the winner, every stake refunds in full.
DRESS THE FLOOR - neon tubes in six colours, patterned casino carpet, card-table felts, chip stacks, velvet stanchions, brass railing, a chasing-light marquee, a giant die, TWELVE table placards (blackjack to hold'em - so nobody has to ask which table is which) and eight hanging pit signs to name your zones: TABLES, SLOTS, ARCADE, HIGH ROLLERS, RACE BOOK, CASINO, WELCOME, DUELS. Plus MARQUEE LETTERS, A to Z in chasing bulbs - spell your casino's name in lights, exactly like the Grand Casino spells its own. All in the Coinkeep shop. There's even a Vending Machine that sells actual food at honest Coinkeep-catalog prices - stock it from config, and by house charter nothing it sells can ever touch the odds. The House Brew is delicious and will not make you lucky.
And the tables look like tables now: the nine card and dice tables are skirted - the body pulls back a pixel and a rail overhangs it, so a blackjack table casts the shadow line a piece of furniture casts and a pit full of them reads as a casino floor instead of a stack of crates. The machines stay cabinets, because a cabinet is supposed to be a box.
AND YOU BUY ALL OF IT - Highroller has no recipes. Not one. Every tube, table and marquee letter comes out of the Highroller tab in the Coinkeep shop, and is paid for with money you earned somewhere else. Anyone can gather wool and gold nuggets; a casino you BOUGHT is a ledger anyone can walk through. Count a rival's tables and you've read their bank statement. The building is the balance sheet. The ladder is short and honest: $50 carpet, $500 a scratch card, $5,000 for a Dice or High-Low table (the entry rung), $15,000-$30,000 for the big tables, $50,000 for the Casino Cage that turns a floor into a business, $250,000 for a Grand Casino in an envelope. All 90 entries in a tab of Highroller's own, sorted cheapest-first - the tab is shipped as data, which is what Coinkeep 1.1.0 is required for. JEI users get the live shop price on every item's info page; JEI stays optional.
REAL ODDS, IN WRITING - Every game publishes its paytable in its own GUI, and those aren't marketing numbers: automated tests enumerate every reel combination, every dice outcome, all 2.6 million poker hands, all 13^6 baccarat coups, all 4096 plinko paths, and a full blackjack strategy solver - every release, or it doesn't ship. An undocumented edge is a scam; ours is on the sign.
YOUR HOUSE, YOUR RULES - Casino blocks are OWNER-LOCKED: what you place, only you (or an op) can break - and a blueprint paste is yours, floor to sign. Per-game switches and stake limits in highroller-server.toml, plus an optional daily-loss cap for servers that want a safety net. Crash, logout or a closed menu mid-game escrows or banks the player's money - live hands wait in the table's NBT for you to come back. The house edge is the only way to lose money that isn't the game itself.
THE FLAGSHIP: TEXAS HOLD'EM - A real multi-seat table: 2 to 6 players, no-limit, real blinds, real betting rounds, real SIDE POTS that survive the ugliest multi-way all-in. Table stakes: buy in from your balance, your stack lives at the table in escrow, stand up to bank it. Hole cards never leave the server until showdown - not even your own client sees the others'. The action clock checks or folds slowpokes (that's the disconnect grace too), and a server restart mid-hand refunds every live bet. 5% rake per pot, floored - and no flop, no drop.
CRAPS, PROPERLY - Pass and Don't Pass through real point rounds, the Field on every roll, the whole rail riding one shooter on timed communal rounds. Pass 1.41%, Don't Pass 1.36% (the 12 bars it), Field 5.56% with 2 and 12 paying double. No odds bets - an EV-zero bet is against the house charter, and the odds page says so instead of hiding it.
THE HOUSE ITSELF - A roadside Saloon and a GRAND CASINO that spells its name in chasing marquee lights spawn naturally in the world: C-A-S-I-N-O across the porte-cochere and down the sign tower, corner towers on the skyline, a slots wall of standing cabinets, a wide-aisled placarded table pit under an atrium, lottery lobby, book corner, a brass-railed high-roller mezzanine up double-wide grand stairs, and a race paddock out back. Or buy the BLUEPRINT and paste either building exactly where you want it - footprint preview, foundations filled to solid ground, front door facing you. It clears its own site and builds through terrain, trees, water and loose blocks, and it stops for exactly four things: anything unbreakable, any container, another player's casino, and a Cage with money in it - naming the block and its coordinates. (It cannot tell your cobble path from a boulder, which is why the first click is always a free preview. Server owners who want the old careful rule set blueprintSiteRule = STRICT.)
LEARN IT IN GAME - the Pit Boss Handbook is in your inventory the first time you join, and it is the whole mod in seven chapters: where the machines are sold, what every published return actually means, the game roster, the betting book, the buildings - and how to stop being a punter and start being the house. The odds chapter is not marketing: it is generated from the same numbers the payout code uses, so the book cannot drift from the machines. Lose it and buy another for $100. No wiki, no external mod, no second window.
TWO QUEST CHAPTERS ship straight into the Coinkeep Ledger. High Roller: 24 one-shot quests on real casino milestones, $69,500 across a full clear, capped by the $25,000 High Roller capstone. The House: five quests that walk you through claiming a Casino Cage, funding it, linking your first table, banking your first losing bet, and counting the take - $15,000 for learning to run a business. (The House needs allowPlayerCasinos on; on a server that keeps the pure sink it simply sits there, and the original 24 still complete without it.) The milestones are real advancements - your players get a whole casino tab.
REQUIRES COINKEEP 1.1.0+ (hard dependency - Coinkeep IS the money, and 1.1.0 is what makes Highroller's own shop tab possible). Updating Highroller to 2.0.0 means updating Coinkeep in the same pass. JEI is optional.
