Blockjack

A casino you build yourself. Eight machines made of small voxels stand in your world as real 3D models: drums turn, balls hop from peg to peg, a wheel clicks to a stop, cards fly out of a shoe, dice tumble out of a cup. Six of them play against the house, two are tables for games between players. Chips you put on a machine are your bet, and its own lever or button plays it. Nothing is given away, and nothing is rigged.

Everything is played for chips, and chips are bought for emeralds.

• Six chips: White 1, Red 5, Green 25, Black 100, Purple 500, Gold 2500.
• Cashier: hold emeralds up to it and they become chips, ten for each emerald. Hold chips up to it and they become emeralds again at the same rate; what does not make a whole emerald comes back as chips. Nothing is lost on the way in or out.
• Change: chips turn into the next ones up and back in the crafting grid: 5 White are 1 Red, 5 Red are 1 Green, 4 Green are 1 Black, 5 Black are 1 Purple, 5 Purple are 1 Gold.

Every game against the house is played the same way: first the bet, then the start.

• Build the bet: right-click a machine with a chip and the chip joins your bet. Keep the button held and the chips keep coming. The machine shows the pile and counts it in its digits, and it waits.
• Play it: each machine has its own control for that. The slot machine has its arm, the plinko board, the lucky wheel and the blackjack table have a blue button with a triangle, and the roulette table has its wheel.
• Take it back: right-click with a hand that holds no chip and the bet is yours again. It also comes back when you walk away from the machine, or when somebody breaks it.
• Yours alone: nobody else can add to your bet, play it or take it.

Put chips in and pull the arm: three drums of eight symbols turn and stop one after another.

• Three alike: coal pays 4 bets, iron 7, gold 12, emerald 25, diamond 60, and three sevens pay 300.
• Two alike on the first two drums pay a little: 1 to 10 bets.
• Nether Star: stands for any symbol but the creeper.
• Creepers: two on the line give 3 free spins, three give 10. The machine plays them by itself with green lamps for the bet that won them, every free win is doubled, and a free spin can win more of them.

Put your bet on the plate and press the button: a ball drops for it, hops down eight rows of pegs, going left or right at each, and lands in one of nine buckets. The buckets in the middle pay 0.2 of the bet, the ones at the edges pay 22 bets. Up to six balls can be on their way at once.

Sixteen segments. Seven of them pay: one pays 5 bets, one pays 3, two pay 2 and three pay 1. The wheel is pulled back and let go, and every peg that passes knocks the red flapper at the top aside, slower and slower until it stops.

A table five blocks long with a turning wheel and one zero.

• Put chips on the felt: a number pays 35 to 1, a dozen or a column 2 to 1, red or black, even or odd, 1-18 or 19-36 pay even money. More chips on a spot raise the bet. The spot you look at is framed.
• The chips of a bet lie beside the sign of their spot, never on it, so the felt can always be read.
• Click the wheel to spin. The ball runs round the rim against the wheel, drops in and settles in a pocket; a marker lands on the winning number, the winners are paid and the rest is taken.
• Several players can bet on the same spin, each on spots of their own.

Put your bet in the ring and press the blue button: the cards come out of the shoe, two for you, two for the dealer, one of those face down. Then the other three buttons play the hand: the green plus takes a card, the red bar stands, and the yellow one doubles.

• A blackjack pays 3 to 2, a win pays even money, equal totals give the bet back.
• The dealer draws to 16 and stands on every 17.
• Doubling takes your bet once more out of the chips you carry and deals exactly one more card.
• Every hand is dealt from a fresh shoe, there is no split, and the table seats one player at a time.

Two tables are not the house's at all: two to four players sit down at them and play each other for a pot of their own chips.

• Sit down: every side of the table has a ring, and a free seat shows the table's stake, with the owner's cut under it if the table takes one. Click the ring and the stake goes from your chips into the pot. Click it again before the round and you get up with your stake. When two players sit, the round starts after a short wait, or at once when every seat is taken.
• Card Duel Table: twenty-one against each other. Everybody gets two cards, and nobody but you sees yours. In your turn the green button takes a card and the red one stands. Go over 21 and you are out. When everybody has stood the hands are turned up and the best one takes the pot; an ace with a ten-card dealt together beats every other 21, and equal best hands share.
• Dice Duel Table: in your turn click your cup, and two dice tumble out of it. The highest total takes the pot; players with equal best totals throw again.
• Fair by construction: the table has no chips of its own. Every chip of the pot is paid out again, and the cards and the dice are the same chance for every seat.
• Turns have a time: a player who does not act in time stands, or has the dice thrown for them. Nobody can leave in the middle of a round.

The player who puts a table for players down owns it. The Table Key, crafted from an emerald over a gold ingot, opens the table's settings when its owner right-clicks the table with it.

• Stake: what everybody puts into the pot, from 1 to 2500 chips.
• Seats: two, three or four.
• Turn time: 10 to 60 seconds for a turn.
• Wait for players: 3 to 30 seconds before a round starts with the players who sit.
• Owner's cut: 0 to 5 percent of every pot for the owner of the table. It is the only thing a table takes, it is nothing unless the owner sets it, and a table that takes one says so on every free seat.
• Reset puts everything back to the standard: a stake of 10, four seats, 30 seconds, 5 seconds, no cut.

The settings can only be changed between rounds, and never the cards or the dice. A table that is taken down keeps its settings on its item and has them again where it is put down.

The house wins slowly. In the long run every game against it pays back most of what is bet:

• Blackjack Table: 99.1% if you play every hand the best way.
• Roulette Table: 97.3% on every bet.
• Plinko Board: 95.8%.
• Slot Machine: 94.5%, free spins counted.
• Lucky Wheel: 93.8%.

A payout smaller than one chip is kept by the machine and added to its next payout, so the odds are the same whatever chips you bet. At the tables for players there are no odds: what the players put in is what the players get out.

1. Craft a Cashier: every machine of the mod is crafted round one emerald, and the recipe book shows the recipes once you have held an emerald.
2. Hold emeralds up to the cashier to get chips.
3. Craft a machine and put it down. The bigger ones need room: the roulette table is five blocks long and two deep, the tables for players are two by two.
4. Put chips on the machine and use its lever or button.

• For NeoForge on Minecraft 1.21.1. The mod is needed on both the client and the server.
• A machine is one item however many blocks it stands in, and one item to a slot: break any of its blocks and all of it comes back.
• Chips are never lost. Breaking a machine gives back what lies on it, and what a machine owes a player who has left the game waits for them until they are back.
• A round is played out. A machine cannot be broken in the middle of a round, so a bet that is about to lose cannot be saved by taking the machine down.
• What you win goes into your inventory, or drops at your feet when it is full.
• The machines give light, enough to play by in a dark hall.
