Bedrock Titan

1. 01

   Draw k is int(k, W), W = 299 being the sum of the symbol weights; the symbol is the one whose weight range the value falls in. Weights, in the order Marra Stonevein, Countess Prismgrave, Seismic gauntlet, Prism sceptre, Crumble, Rubble chunk, Rebar knot, Hard hat, Cracked tile, Shockwave, Quake core: 10, 16, 20, 24, 28, 40, 44, 48, 52, 8, 9.

2. 02

   The first 15 draws fill the grid column by column, top to bottom. A wild drawn on reel 1 or 5 becomes the last low symbol.

3. 03

   Each cascade refills the cleared cells with further draws: columns left to right, top to bottom.

4. 04

   The smash takes no extra draw: when a cascade goes on, every cell of a smashed reel (one holding a winning Marra Stonevein, or in the free spins a winning Shockwave) is cleared with the winning cells, and a smashed reel is refilled one draw per cell, top to bottom, like any other cleared cell.

5. 05

   Free spins run the same way on the same stream; a bought feature has no spin before it, so its draws begin at k = 0 with its first free spin. The whole spin, feature included, is reproducible from one nonce.

float(k) and the rest of the notation are defined in the byte stream.

5 reels × 3 rows, 243 ways, left to right. Winning symbols clear and new ones fall in; each cascade in a spin climbs 1× → 2× → 3× → 4× → 6×. Wilds land on the three middle reels.

When Marra Stonevein is part of a win, after the win is paid she smashes every reel her symbol won on: the whole reel clears, the cells that did not win included, and new symbols fall in. Smashed cells pay nothing. Aftershock: in the free spins a winning Shockwave smashes its reel too. A smash happens only when the cascade goes on, so not on a spin's last drop or one that reaches the cap. About one spin in 269 has a smash.

3, 4 or 5 scatters on the first drop of a spin award 8, 10 or 12 free spins; 3, 4 or 5 on a free spin add that many again, up to 60 free spins in all. The feature can be bought for 7.99× the bet with 8 free spins, for 9.99× with 10, or for 12× with 12. Each price is what those spins return on average, less the house's share: no tier is a better buy than another.

Bought, the three return 96.19%, 96.16% and 96.17%, as measured (each give or take 0.18 points at most); most buys return less than they cost.

When two scatters are in view, the reels still turning stop more slowly. That is decided only by the reels that have already stopped and happens every time two are in view, whether a third comes or not: it says nothing about what the turning reels will show.

One spin, feature included, pays at most 5,000× the bet: a spin that reaches it stops there and is paid exactly that.

The return printed here was measured, not derived: 96.17%, give or take 0.08 points, over 60 million spins. 36.1% of spins pay something; the free spins come about one spin in 106 and pay 8% of the return.
