Punk Rocker

What these figures mean for Punk Rocker

There is a number missing from this game's specification, and finding it is the most useful thing you can do with the figures Nolimit City does publish. The game returns 96.01%. The base game returns 42.84% — the lowest base-game figure of any title in this catalogue, and nearly eight points below the next lowest, the 50.7% of Finn and the Swirly Spin. Subtract one from the other and 53.17 percentage points of return are unaccounted for. The studio states no bonus-round RTP for Punk Rocker, so where those 53 points live is something you have to reason out rather than read.

The answer is in the two odds figures. Free spins arrive once in 244 spins, which is the longest wait of any Nolimit City game here. And a win of 100x your stake or better comes once in 1,789 spins — again the longest in the catalogue, nearly three times the 635 spins of Das xBoot. Put those together and the shape is unmistakable: more than half of everything this game gives back is locked behind features you reach, on average, once in every £244 of £1 spins, and the ordinary game you play while waiting hands back under 43p in the pound.

That is worth stating plainly, because 42.84% is not a number most players have ever seen attached to a slot. If the base game were the whole product, it would be one of the worst-value gambling propositions available anywhere — worse than almost any casino table bet, worse than most lotteries' headline odds. It is not the whole product, and the 96.01% is genuinely delivered over the long run. But the distribution means that for long stretches, what is actually happening at the machine is a 43% game.

Compare it with Dead or Alive 2, which NetEnt rates at a volatility index of 9.9 against the 9.96 Nolimit City publishes here. By that measure these two games are twins — six hundredths of a point apart on a scale that runs to 66.85 in this catalogue. Now look at what they do with that identical dispersion. Dead or Alive 2 pays its base game 68.6% and tops out at 1,600x. Punk Rocker pays its base game 42.84% and tops out at 15,072x — nine times higher. Same measured volatility, completely different machines: one gives you a reasonable game to sit in and a modest ceiling, the other strips the base game to the bone to fund a top prize nine times the size. The index tells you how bumpy the ride is. It says nothing about which direction the game has been engineered in, and these two are the proof.

The hit frequency rounds the picture out at 21.38%, so roughly one spin in five returns something. That is a little below the 22.17% of Das xBoot and the 24.58% of Karen Maneater, and nowhere near as sparse as the 9.08% of Tombstone R.I.P. What is unusual is the combination of an ordinary-for-this-studio hit rate with a 42.84% base return: the hits are landing about as often as in its stablemates and still returning less than anything else here, which means they are smaller. Frequent, small, and adding up to under half your stake back. That is what the missing 53 points cost you in the part of the game you actually spend your time in.

The feature buy, then, is doing something different in this game than in most. Everywhere else in this catalogue, buying the bonus skips a base game returning somewhere between 50.7% and 68.7%. Here it skips one returning 42.84%, which is the strongest mathematical case for a buy anywhere on this site — you are escaping the worst stretch of play in the catalogue. Whether the price charged makes it worthwhile is a different question, and one we cannot answer: the cost is set in the game client, we have not checked it at any operator, and a buy priced above its expected value is a bad deal no matter how poor the base game is. The structural argument is real; the arithmetic that would settle it is not available to us.

One point of fairness to the studio. Nolimit City is the only studio in this catalogue that publishes the odds of a 100x win, and it is those published odds that make this game's shape visible at all. For Twin Spin or Gonzo's Quest, NetEnt states no equivalent figure — a game could have a 1,789-spin wait for a 100x and nothing in its specification would say so. Punk Rocker looks harsh here partly because it is harsh and partly because the studio tells you. That asymmetry is worth holding onto when a game with less published detail looks friendlier.

So: the game with the meanest base in this catalogue, the longest wait for a meaningful win, and a top prize nine times that of a game with identical measured volatility. If you play it, you are paying for the ceiling with the floor, and the studio has published enough for you to see the exact exchange rate.
