Chrome stools, a neon sign in the window and a row of tall glasses on the counter. Milkshake XXXtreme is NetEnt's diner slot, and the glasses are the whole game: every win you land pours into one of them, and when a glass fills up, it multiplies what the spin pays.
The grid is six columns by six rows of ice cream scoops and boiled sweets. There are no paylines to learn. Eight or more of the same symbol anywhere on the grid pay, and that's the only rule you need before your first spin.

What each symbol pays
Every symbol pays more the more of it there are on the grid, in four steps: 8 to 12, 13 to 16, 17 to 21, and 22 to 36. The prizes grow with your bet, so the table gives them as proportions: a sweet in the smallest group (8 to 12) is 1, and everything else is measured against it.
| Symbol | 8–12 | 13–16 | 17–21 | 22–36 |
|---|---|---|---|---|
| Red scoop | 2 | 3.5 | 7.5 | 10 |
| Chocolate scoop | 1.5 | 3 | 6 | 7.5 |
| Mint choc chip scoop | 1.4 | 2.5 | 5 | 6 |
| Blue scoop | 1.2 | 2 | 4 | 5 |
| Heart, diamond, club or spade sweet | 1 | 1.5 | 2.5 | 4 |
So a grid with 22 or more red scoops pays ten times what eight sweets pay. Only the highest prize for each symbol is paid per combination. The Wild, a red carton of milk, can land anywhere and stands in for every other symbol, so it can turn seven of a kind into eight.
Avalanches
When a win lands, every symbol in it bursts and disappears. The symbols above drop down, new ones fall in from the top, and if that makes another win, it bursts too. This is NetEnt's Avalanche, and it carries on until the grid settles with nothing left to pay. A single spin can pay more than once, and every one of those wins pours into the glasses.
The milkshake glasses
This is where Milkshake XXXtreme earns its name. At the start of each spin, one glass joins the counter beside the grid. The game gives it a colour (red, green, orange or blue), a multiplier between x2 and x100, and a head start of between 2 and 12 points.
Wins in the glass's colour top it up with points, one for every symbol in the win, so a win of ten red scoops adds ten points to a red glass. Once a glass reaches 20, it disappears, its multiplier is kept for the end of the spin, and two new glasses take its place, up to four on the counter at once. When the grid finally settles, everything the spin paid is multiplied by the multipliers of every glass that emptied along the way, added together. Fill a x3 and a x5 in the same spin and the whole spin pays eight times over.
Boosters
Now and then a glass arrives with a Booster. A Multiplier Booster swaps its multiplier for a bigger one, from x4 up to x100. A Colour Booster turns it into a Rainbow Milkshake, which keeps its multiplier and points but fills up from wins of any colour, not just one.
XXXtreme Spins
The button beside the grid switches on XXXtreme Spins, a dearer spin with a better start:
| Cost per spin | What you start with |
|---|---|
| 10× your bet | 2 glasses, and 1 Wild that always lands |
| 95× your bet | 4 glasses, and 2 Wilds that always land |
They stay on, spin after spin, until you press the button again to switch them off. At a bet of 1.25, for example, the two options cost 12.50 and 118.75 a spin, so it's worth a look at the button before you press Spin.
Back at the diner
Milkshake XXXtreme is one stop on our road trip. It sits with Reelin' & Rockin' and the rest of the diner on Vegas Slots, between the Vegas Strip and the Wild West.
