30 Boost Clover

30 Boost Clover is a fruit slot from Felix Gaming, released on 13 November 2025. It plays on a 5x3 grid with 30 lines and takes bets from €0.30 to €120. Felix publishes a maximum exposure of 2,000x the total bet. The idea that gives the game its name is the Line Boost: you pay extra on individual paylines to multiply what they pay.

A Clover In The Undergrowth

The reels stand in a dark green forest at night, lit from behind so that the fruit glows. The 30 BOOST CLOVER logo runs down the left of the frame with a LINE BOOST plaque under it, and a strip labelled « CHOOSE LINE » sits across the top with miniature diagrams of the paylines on either side, so you can page through them without leaving the reels.

The symbols are classics: cherries, lemons, oranges, plums, grapes, watermelons, a golden bell, a red 7 and a blue diamond. A four-leaf clover is the wild and a gold dollar sign is the scatter.

The Line Boost Panel

Press the plaque and the reels are replaced by a grid of all thirty lines, each drawn as a little 5x3 diagram with its own x2, x3 and x5 buttons and a BOOST switch. The header spells it out: “Boost your favorite lines with x2, x3 or x5 multiplier”. Along the bottom are CLEAR, CONFIRM and ALL LINES, and the total bet is displayed on both sides of them.

In our screenshot the base bet was 0.90 – thirty lines at 0.03 each – and with a handful of lines switched on at x2 the total had risen to 1.11. You pay the surcharge only on the lines you pick, so the cost scales with how greedy you are rather than doubling the whole stake.

Boosts On The Reels

Once confirmed, the boosted lines are marked directly on the grid. Small x2 badges appear under the symbols that sit on a boosted line, so you can see at a glance which of the winning combinations is being multiplied. One of our screenshots shows three of them in a row along the bottom of the reels.

At a total bet of 29.60 the boosted spins in our session paid 72.00, 208.00, 216.00 twice, 304.00 and 368.00 – between 2.4x and 12.4x the stake. The balance ticked along from 99,911.20 down to 99,366.40 across those spins, so the boosts were roughly paying for themselves rather than transforming the session.

The Paytable

The line values are printed at the stake you are playing. At our bet the five, four and three of a kind figures were:

Diamond – 1,600.00 / 160.00 / 32.00, and 4.00 for two
Red 7 – 800.00 / 80.00 / 16.00
Bell – 400.00 / 80.00 / 16.00
Plum – 320.00 / 64.00 / 16.00
Watermelon and orange – 160.00 / 32.00 / 8.00
Grapes, lemon and cherry – 80.00 / 16.00 / 8.00

The diamond is the only symbol that pays for two of a kind, and it pays twenty times more for five than the fruit does. Note that these are per-line amounts – the 2,000x maximum is reached by filling many of the thirty lines at once, not by one lucky payline.

The Dollar Scatter

The scatter works differently, and the rules screen says so: it “appears on all reels” and “pays on any position”. Its values are the ones tied to the total bet rather than a line: at our 29.60 stake, five scatters paid 14,800.00, four paid 592.00 and three paid 148.00 – 500x, 20x and 5x the whole bet.

The Expanding Clover

The wild rule is unusually specific. The rules state that the clover “appears on all reels”, that it “will expand and substitute for all symbols in all positions on that reel”, and – the important part – that the “wild symbol will only expand if a winning combination is possible”. It substitutes for everything except the scatter.

That last condition is what keeps expanding wilds honest here. A clover that lands where it cannot complete anything simply stays a single symbol. When it does expand, it fills its whole reel, and on a 30-line game that usually means several lines paying together – our 304.00 and 368.00 wins both came from expanded clovers.

Three RTP Versions

Felix Gaming publishes the return for this game as a set rather than a single figure: 96.06%, 94.61% and 92.40%. Casinos choose which version to run, and the spread between the top and the bottom setting is more than three and a half points – a bigger gap than most players expect. The reels, the boost panel and the paytable are the same in all three; only the return changes.

What The Bet Changes

Everything above scales with the stake. The boost panel screenshots were taken at a 0.03 line bet and the reel screenshots at a 29.60 total bet. At the €0.30 minimum a five-diamond line is worth around 16, and at the €120 maximum the same line is worth around 6,400 – before any boost multiplies it by two, three or five.

More From Felix Gaming

The Boost family is Felix’s signature. 10 Boost Clover is the ten-line version of exactly this game, with the same clover wild and the same boost panel on a smaller grid, and the casinos we checked carry both side by side.

Who It Is For

30 Boost Clover is for players who want a say in their own variance. The base game is a plain fruit machine with an expanding wild; the Line Boost is what turns it into a decision. Boost nothing and you have a cheap, low-key classic. Boost five lines at x5 and you have a far more volatile game for a fraction more stake – and the 2,000x ceiling starts to look reachable.
