    BetsRank Verdict

    Hands-on testing by Alexandre Dubois — bonus tested, multiple sessions

    Chance Machine 100 shows the Endorphina method on classic machines: few mechanics, but mechanics that turn up often. The two scatters, one of which pays from three occurrences, give the base game a rhythm most hundred-line classics simply do not have, and the expanding crown wild on the middle reels fills a four-row grid efficiently. The 96.07% RTP is the highest in the series, which is not a trivial detail when the four entries sit within six hundredths of one another. BetsRank sees an honest, well-calibrated title whose main limit is structural: without free spins or a bonus buy, the amplitude stays bounded, and the potential quoted by third-party databases still needs confirmation from the studio. The diamond and crown presentation is neatly done without surprising anyone. For a player who wants a readable grid and a steady tempo rather than a long wait for a feature to open, that trade-off is a reasonable one to accept. This is a solid catalogue filler, played from a one-euro minimum stake.

    Strengths

    • +Official RTP of 96.07%, the highest in the Chance Machine series.
    • +Two distinct scatter symbols, one paying from three occurrences anywhere on the reels.
    • +Crown wild that expands vertically across reels 2, 3 and 4.
    • +Dense, readable 5x4 grid at a hundred fixed lines, with no rules to learn first.
    • +Medium volatility as stated, consistent with the grid density and the second scatter.

    To consider

    • No free spins mode: the scatters pay out, they do not open a feature.
    • No Bonus Pop, confirmed by Endorphina, so the bonus cannot be bought.
    • No win cap published by the studio, leaving the real potential imprecise.
    • A 1 EUR minimum stake imposed by the hundred fixed paylines.

    Chance Machine 100: Endorphina's gold classic at a hundred lines

    Chance Machine 100 belongs to a family of classic machines from Endorphina, split by line count: Chance Machine 5, Chance Machine 20, Chance Machine 40, and this hundred-line version. The studio announced its worldwide release on 14 July 2020, after a pre-launch period restricted to a handful of casinos.

    Despite what the word "classic" usually signals in this genre, there is not a single fruit on the reels. Endorphina describes a world of cut diamonds, gold finishes and rich colours, with a royal crown, a bell and combinations of sevens as the headline symbols. The seven is the best-paying symbol in the game: five in a row are worth 30x the base bet on the official paytable.

    The grid runs five reels by four rows, for a hundred fixed paylines. Two mechanics give the game its shape.

    • The crown wild appears only on reels 2, 3 and 4. It substitutes for every symbol except the scatters and expands vertically to complete a combination, which lets it cover the full height of a reel.
    • Two separate scatter symbols count anywhere on the reels, with no need to land on a payline. The paired golden stars pay 100x the base bet for five; the single white star pays 20x the base bet from three occurrences.

    On top of that sits the Risk Game, the studio's usual card gamble offered after a win. What the game does not have is a bonus buy: Endorphina states in the official FAQ that Chance Machine 100 does not carry the Bonus Pop feature, unlike several other titles in the catalogue where it appears at a lower RTP than the base game and depends on the jurisdiction.

    The published parameters give an RTP of 96.07% and medium volatility, with a stake range of 1 EUR to 80 EUR per spin. The studio does not publish a win cap; specialist databases quote an order of magnitude around 3,000x the stake, a figure best treated as indicative until Endorphina confirms it.

    In terms of how the game actually plays, the presence of two scatters changes the rhythm more than the line count does. A scatter that pays 20x the base bet from just three occurrences turns up far more often than a conventional bonus trigger, and that gives the base game a breathing space the five- and twenty-line entries in the series never had. The crown wild, confined to the three middle reels, plays a similar supporting role: it opens no feature, but it finishes off lines already part-formed on a dense grid. That architecture is what puts the game at medium volatility, between the low rating of Chance Machine 20 and the medium-high rating of Chance Machine 40. The title runs on mobile and tablet with nothing to install.

    • Both scatters count anywhere on the reels, with no payline requirement attached.
    • Seven as the top-paying symbol, at 30x the base bet for five in a row.

    Frequently asked questions about Chance Machine 100

    What is the RTP of Chance Machine 100?

    Endorphina states 96.

    07% on the official game page and confirms it in the FAQ. That is the highest figure in the series, ahead of Chance Machine 40 at 96. 06%, Chance Machine 5 at 96. 02% and Chance Machine 20 at 96. 01%. The paytable displayed by your casino remains the final reference.

    How volatile is Chance Machine 100?

    The studio rates it medium.

    That position follows from the density of the 5x4 grid at a hundred lines and from the second scatter, which pays from three occurrences and therefore lands often. Some third-party sources describe it as low; the classification used here is the one Endorphina publishes.

    Can you buy the bonus on Chance Machine 100?

    No.

    The studio's official FAQ states that this game does not carry Bonus Pop, the name Endorphina gives its bonus buy. There is therefore no purchase price for this title, and the scatter payouts are reached through the base game only, exactly as the paytable describes them.

    What is the maximum win on Chance Machine 100?

    Endorphina publishes no overall cap on its official sheet.

    Specialist databases quote an order of magnitude around 3,000x the stake, a number worth treating as indicative rather than confirmed. The highest documented payout remains the golden scatter at 100x the base bet for five occurrences.

    How does the crown wild work?

    The crown substitutes for every symbol except the scatters, but it only appears on reels 2, 3 and 4.

    When it contributes to a combination it expands vertically to cover the full height of its reel, which on a four-row grid lets it complete several paylines at the same time rather than just one.

    Why does Chance Machine 100 have two scatters?

    Endorphina split the rewards into two levels.

    The paired golden stars carry the high payout at 100x the base bet for five occurrences. The white star pays 20x the base bet from three occurrences and acts as the frequent top-up. Both count anywhere on the reels rather than on a line.

    Is there a theme of fruits in this game?

    No.

    Despite the classic slot format, Endorphina built the artwork around cut diamonds, gold finishes and rich colours, with a royal crown, a bell and combinations of sevens as the leading symbols. The seven is the best-paying icon on the paytable, worth 30x the base bet for five in a row.

    How does it differ from Chance Machine 20 and 40?

    Chance Machine 20 runs on a 5x3 grid with twenty lines, an RTP of 96.

    01% and low volatility. Chance Machine 40 moves to 5x4 with forty lines, 96. 06% and medium-high volatility. Chance Machine 100 keeps the 5x4 grid, climbs to a hundred lines, 96. 07%, and lands at medium volatility.

    Does the game offer free spins?

    No.

    Endorphina sums up its features as classic gameplay, two distinct scatters, expanding wilds and the Risk Game. There is no free spins mode triggered by the scatters: they pay out directly when enough of them land on the reels, without opening a separate bonus screen at any point.

    Can Chance Machine 100 be played on mobile?

    Yes.

    The studio states the game is available on any mobile or tablet. No app is needed, since the session starts from the browser or from the casino's own app. The grid stays readable in portrait, and the paytable can be opened from the in-game menu at any time.

    What are the minimum and maximum stakes?

    The official page lists a range of 1 EUR to 80 EUR per spin.

    The one-euro floor follows directly from the hundred fixed lines, which cannot be switched off individually. Casinos can narrow that range depending on their jurisdiction or on the terms of a bonus you have running.

    Who is Chance Machine 100 for?

    It suits players who like classic machines and prefer a dense grid to a complicated feature set.

    With no free spins and no bonus buy, everything rests on line frequency and on the two scatters. A bankroll suited to the one-euro floor per spin is the most concrete practical requirement here.
