MooFo

MooFo is a 5x3 slot from Endorphina, released on 9 July 2026, running 30 fixed paylines at an RTP of 96.05% with high volatility. The premise is alien abduction on a working farm, the pun density is extreme even by this studio’s standards, and underneath all of it sits a perfectly conventional three-bonus structure.

Three UFOs, Three Bonus Games

Hovering above the reels are three flying saucers, each with a different abducted farm animal visible through its dome and each labelled with the round it opens. The green one holds a goat and reads UFO GAMES. The red one holds a cow and reads MILK’EM. The purple one holds a chicken and reads MOO HOLD.

This is the same architecture Endorphina used for the crystal balls in Zalatar and the bucket hats in Groovin’ Tiger – three named rounds, permanently displayed, so you always know what the game can give you. Here the three are a free-games round, a pick round and a hold-and-win, which covers the standard bases without pretending otherwise.

The Moo Hold Round

One screenshot catches the hold-and-win in progress, and it is the clearest look at how the game actually pays. The banner along the bottom of the reels reads “YOU WON THE MOO HOLD BONUS GAME!”, the purple saucer above has gone dark because it is the one in play, and the grid has filled with metallic orbs carrying cash values.

Against a €21.00 bet those orbs read €126.00, €189.00 and three at €84.00 – that is 6x, 9x and 4x the stake sitting on the board at once, with the tractor and scarecrow symbols still occupying the cells that have not locked yet. Compared with the base paytable these are enormous numbers, which is the point.

The Barn And The Jackpot Ladder

A second screenshot shows the round in its developed state, and the game has moved house. The field is gone; the reels now sit inside a barn lit in deep purple, hay bales stacked behind them, lanterns strung from the rafters, the grid framed in yellow-and-black hazard tape.

Along the top runs a jackpot ladder that the base game never shows: MIN €1,050.00, MID €2,100.00, MAX €6,300.00 and, set apart in orange, ULTRA €21,000.00. At the €21 stake those are 50x, 100x, 300x and 1,000x. A respin counter sits beside them showing 5 remaining.

The board in that shot is well filled – €126.00, €189.00, €147.00, €63.00, €42.00, €21.00 and three more at €84.00, with a handful of cells still showing the ghosted cow that marks an empty position. Add the Ultra’s 1,000x to a board like that and the game’s 1,500x ceiling stops looking arbitrary: the jackpot is two thirds of it, and the orbs are the rest.

A Farm Paytable

The paytable is shown at the minimum €0.30 stake, which makes the multiples easy to read. The thinking goat leads at €12.00 for five, €3.00 for four and €0.60 for three – 40x, 10x and 2x the base bet. The happy pig follows at €9.00 for five, or 30x.

Behind them the chicken and the green tractor both pay €3.00 for five – 10x – and then the floor drops out. The cow-patterned boot, the UFO milk carton and the scarecrow all pay €0.30 / €0.15 / €0.05, meaning five of a kind of the three most common symbols returns exactly your stake.

A 40x top symbol against a 1,500x maximum win tells you where the variance lives. Thirty lines keep the reels busy, but the base game is a waiting room; the saucers are the game.

The Guard Dog Wild

The wild is a growling guard dog, and it is positionally restricted: it appears on reels 2, 3, 4 and 5 only, never the first, in both the main game and the Free Games. It substitutes for everything except the Bonus symbols and the Tokens.

Keeping wilds off reel one trims the hit rate on long left-to-right lines, and it matters here because thirty lines would otherwise make the dog far too generous. The screenshots show it turning up singly rather than stacked, with wins in the €22 to €31 range against the €21 bet.

Cow Tokens

The Tokens are green, red and purple cows, colour-matched to the three saucers, and they appear in both the main game and the Free Games. They land on top of other symbols and hide them; when they fly off, whatever was underneath is revealed and can complete a line that was not visible a moment before.

It is the studio’s house mechanic by now, but the theme carries it better than usual – a cow lifted off the reels by a tractor beam is a more natural animation than a coin simply vanishing.

The Risk Game

Endorphina’s card gamble is present and runs up to ten doublings. Beat the dealer’s face-up card with one of the four face-down options and the win doubles; take it at any rung and it stops. On a game whose base wins hover around one to two times the stake, ten rungs is a very fast way to turn small change into something worth having – or into nothing at all.

Presentation

The art is warm and genuinely funny. The reels are painted onto a wooden farm sign nailed out of planks; behind it a field runs into a deep blue evening, a farmhouse glows on the right, and a purple saucer hangs at the left edge with its beam down. The symbols are chunky and cartoonish – the goat looks worried, the pig delighted, the dog furious. Endorphina pitches the whole thing as the follow-up to its earlier Cows & UFOs, which is where the abduction premise came from.

RTP And Stakes

The 96.05% RTP is the studio’s usual figure and the high volatility rating is accurate: with three of the seven regular symbols paying only the stake back for five, most spins go nowhere.

Bets run from 0.3 all the way to 180, which is a far wider range than the cartoon presentation suggests – this is not only a small-stakes machine. The bottom bar carries FIXED LINES 30, CURRENCY and BET with TURBO, AUTO and SPIN opposite, and a strip that names each paying line as it lands.

Who It Is For

This suits players who want a bonus-led slot with some personality and do not need a five-figure ceiling. The three-saucer structure is legible from the first spin, the Moo Hold round pays in genuinely large multiples of the stake, and the whole thing is put together with more care than a farm-animal pun-fest has any right to be.

The reservations are the flat bottom half of the paytable and the 1,500x ceiling. If you want a base game that pays its own way, this is not it, and the wild’s absence from reel one makes the quiet spells quieter. What you get in exchange is three distinct bonus rounds, a stake range that stretches from thirty cents to a hundred and eighty euros, and the best-looking cow abduction on the market.
