Dice House

Verified against the spelunky.ai port v0.1.10 on 28 October 2026.

Its Shopkeeper welcomes the player with "WELCOME TO LEMMY'S DICE HOUSE!", his name one of 32 drawn at random, and "PRESS P TO BET $2000.", the bet's price on level 2 ^{[7] [8]}. It has no wares for sale: it has two dice on its floor, a sign of the rules on its wall, and a prize behind two blocks of ice at the back, which only a throw of 7 wins ^{[2] [9] [10]}. Outside the Black Market, it's a side room off the way through a level like every shop, with the Shopkeeper on a ledge above the floor.

The pay key in the shop bets: the bet comes out of the player's money ("YOU BET $2000! NOW ROLL THE DICE!"). Pressed again while a bet is on, it says "ONE BET AT A TIME!", and without the money, "YOU NEED $2000 TO BET!". A thief, or a killer of Shopkeepers, gets nothing ^[11]. The dice are picked up and thrown like any item. Each shows a number from 1 to 6, and rolls a new one on every step it moves faster than 2 pixels a step; thrown while a bet is on, it's rolling, and it counts once it comes to rest on the ground ^[12]. When both have, the Shopkeeper adds them up ^[13]:

Either way the bet is settled and both dice are ready to throw again. He settles only while he's calm and near the screen, and only with both dice still on the level ^{[17] [18] [19]}. In the clip, the player bets $2,000 and is refused a second bet; the dice come up 4 and 5, and his $1,100 counts up to $5,100 ^[20].

The prize is rolled from a set of the dearer items: each roll is tried in turn until one hits, and a Bomb Box if none does ^{[21] [22]}:

Unlike a shop's wares, a prize is rolled without checking what the level already has, so it can be a second Compass or pair of Gloves. On a 7, the prize jumps 32 pixels toward the player, out of its case and free, and a new one from the same set appears in the case, the next 7's ^[36]. In the clip, the dice come up 5 and 2: the case's Spike Shoes come out in a puff of smoke, a Bomb Box takes their place, and the player picks the shoes up and they go on ^{[37] [38]}.

The bet is $1,000 and $500 for each level, whatever the dice house ^{[39] [40]}:

A win above 7 pays twice the bet, so it gains the player one bet. A prize costs only the bet it's won with: it keeps the price its item is made with, but nothing marks it for sale, and a 7 sets the price to nothing as it frees it ^{[22] [41] [42]}.

The Shopkeeper doesn't follow the player about the shop, as he does where there are wares; he stands on his ledge and settles the bets ^[43]. What angers him in other shops angers him here (the General Store has the rules): the blocks of ice around the prize are the shop's walls, so breaking one in is vandalism, which frees the prize with everything else ^{[44] [45] [46]}. Two things are the Dice House's own, both "COME BACK HERE, THIEF!" ^[47]:

• A die rolled twice. A die that has come to rest and is thrown again before the bet is settled angers him as it lands. The code's comment calls it "NO CHEATING!" ^[48].
• A die out of the shop. A die near the screen outside a shop's room angers him at once, though it has no price ^[49]. The check is for any shop's room ^[50].

In the clip, the player bets again and throws one die, which comes up 5, then picks the same die up and throws it again. As it lands, the Shopkeeper shouts, comes down from his ledge and shoots him dead ^[51].

The Dice House has no wares to steal, but a die carried out angers the Shopkeeper as a theft does, and marks the player a thief for the next level, where the General Store's rules apply ^{[52] [53]}. A thief can't bet ^[54]. A prize in its case has a price, so on a thief's level it's freed and counted as stolen in the end-of-game statistics as it comes on screen, as wares are ^{[55] [56]}.

A level from 2 to 15 that rolls a shop builds one of seven kinds, each as likely, so a shop is a Dice House one time in seven (one in six on a Temple sacrifice pit level, which never has a Kissing Parlor), in every area and on a Yeti lair level too ^{[57] [1] [58] [59]}. The Mines has how levels roll shops. Every Black Market has a Dice House, the third column's third room, where the pay key bets only in that room ^{[6] [60]}.

• The source calls it the "Craps" shop ^[2]. A new game sets a global.crapsPoint to 0 with the other globals, and nothing reads it ^[61].
• The prize's tile rolls a number from 1 to 6 that nothing uses before rolling the prize ^[21].
• The end-of-game statistics count dice games played, won and lost; a 7 counts as won ^{[62] [63]}.
