Chance Machine 100 Slot Review
Wine-red velvet under stage light, a gold frame with fluted bevels glowing down each side: the room looks expensive before a single reel has turned. Chance Machine 100 is a plain fruit machine inside all that dressing, and the money here has gone into the maths rather than the entertainment.
That maths reads as a 98.07% RTP on a 5×4 grid with 100 fixed paylines, no bonus round of any kind, and one card gamble to break up the spins. The return, from Endorphina, sits nearly two points above the typical modern slot and is the reason to notice this cabinet at all. The studio took the same lean approach in Chance Machine 5 Dice and Thunder Crown Dice. On a hundred lines, there’s always something collecting.
One Hundred Lines and a Glossy Paytable
The reels hold a classic fruit-machine cast: red 7s, a bell, a green four-leaf clover, a BAR and the four card suits, all rendered in that same lush, gilded finish as the frame. The suits come colour-coded: blue spades, red hearts, purple clubs, green diamonds.
Wins need matching symbols on adjacent reels from the left, on one of the 100 fixed lines. Scatters are the exception, counting anywhere. Payouts are multiples of the total bet rather than the line bet, which matters on a game with this many lines. The values step up sharply at the top:
- 7: 0.1x for a pair, then 0.5x, 2x and 30x for five
- Bell: pays 0.4x for three, rising to 1x and 5x
- Four-leaf Clover: matches the bell exactly, at 0.4x, 1x and 5x
- BAR: worth 0.2x, 0.5x or 2x
- Spade, Heart, Club and Diamond: the bottom rung, paying 0.1x, 0.3x and 1x
The 7 is the only symbol that pays for two of a kind, and the gap between it and the suits is steep: a full line of sevens returns 30 times the total bet, where a full line of suits returns one. Prizes scale with the selected bet, so the ladder reads the same at every stake.
Only the highest combination counts on each line, and scatter wins are added on top of line wins. The crown wild lands on the middle three reels only, substitutes for everything except the scatters, and expands vertically to complete combinations.
No win cap appears anywhere on the machine; the biggest prizes on the board are five yellow stars and a full line of sevens. Everything above the suits is a long way from the suits.
Two Stars, Two Jobs
There are two different scatter stars, and they don’t behave alike. The yellow scatter can appear on any reel and pays 3x for three, 20x for four and 100x for five, at any position. The white scatter only appears on reels one, three and five, and pays 20x for a set of three.
Neither triggers a bonus round. There is no free spins feature in this game at all, which is the honest shape of it: scatters here are prize symbols, not doorways. Five yellow stars at 100x the total bet is the richest single payout the paytable offers.
Because both stars count wherever they land, a reel can carry a scatter without it touching a payline at all. On a 100-line game that’s a meaningful mercy: the stars don’t need help finding each other.
It also means a spin can pay twice from unrelated symbols, since scatter wins and line wins are simply added together. A line of sevens on the left and a stray star on the right both go in the pot.
The Risk Game
After any win, the Risk Game offers to gamble it. Four face-down cards are dealt against the Dealer’s card: beat it and the win doubles, with up to ten attempts to keep going. Lose one round and the winnings are gone. The TAKE WIN button collects and quits at any point.
The Joker beats everything, and the Dealer can never draw one. A matching value is a draw: the win stands and another attempt is allowed. Card probabilities aren’t equally distributed, and cards can reappear between rounds, so each decision genuinely depends on what’s showing.
The odds per Dealer’s card swing enormously, and knowing them is the whole skill of the round. Against a 2 the return is 162%; against an ace, just 42%. The full ladder:
- Dealer shows 2: 162% return
- 3: 121% 4: 113% 5: 101%
- 6, 7 or 8: 100% 9: 92%
- 10: 78% J: 69% Q: 66% K: 64%
- A: 42% return
Read that ladder as a rule of thumb: anything from a 6 to an 8 is a fair coin for your money, a deuce or a trey is worth doubling into, and a picture card is where sensible gamblers take the win. The averages confirm it.
Taken blind every time, the gamble averages an 84% return, so the doubling ladder is a losing proposition in the long run. Played with a stop-loss against weak Dealer cards, it’s the closest thing this game has to a skill decision. It’s the only branch in the whole machine.
Our Honest Verdict
Overall Rating: 6.2/10
Playing Chance Machine 100 is sitting at a quiet table in that wine-red room: the reels turn, small wins land across a hundred lines, and the gilding barely moves. The one reason to choose it is the return, because 98.07% is about as generous as this format gets, and you feel it in how often the balance ticks up rather than in any single win.
The Risk Game is the best thing here. The Dealer’s card turns a guess into a decision, and the odds ladder rewards actually reading it: double into a deuce, take the win against an ace. The weakness is that nothing else happens. With no free spins and no bonus round, the stretches between gambles are just spins, and the top of the paytable won’t quicken a pulse.
Chance Machine 5 Dice did the same job with rather less waiting, and it’s the leaner game of the two. Chance Machine 100 is for players who like old machines, generous maths and the nerve to double into a deuce; anyone chasing feature rounds will find louder rooms elsewhere in the Endorphina catalogue. For the patient, the gilt is worth sitting in.
