Lists of “secret slots” regularly contain titles that do not exist. Here there are only games you can look up in their studio’s catalogue.
The joker is one of the oldest motifs in slot play and appears at almost every major studio. Plenty of lists circulate accordingly — and many of them contain titles that appear in no catalogue.
So here is the check first and the selection second: every title named can be looked up at its studio or in an operator's game catalogue. Where that is not possible, the question about a game's properties is already answered.
Joker slots that exist
| Title | Studio | Build |
|---|---|---|
| Mega Joker | NetEnt | Classic, with Supermeter mode |
| Joker Pro | NetEnt | Classic, fixed lines |
| Jokerizer | Yggdrasil | Classic, Jokerizer mode |
| Joker Millions | Yggdrasil | Progressive jackpot |
| Fire Joker | Play’n GO | Three reels, wheel feature |
| Sticky Joker | Play’n GO | Classic, sticky wilds |
| Joker’s Jewels | Pragmatic Play | Five reels, few lines |
| Joker Strike | Quickspin | Classic with strike zone |
The “build” column is deliberately general. Return figures and maximum wins are intentionally absent: the same title runs in different configurations at different operators, and the only valid number is the one in the information panel of the game in front of you.
The four figures you compare with
- Return figure. The long-run return. Between 96 % and 94 % lies a 50 % difference in expected loss at the same turnover.
- Volatility. Determines how long an ordinary dry spell lasts — and therefore whether the budget matches the intended playing time.
- Maximum win. The ceiling per round, as a multiple of the stake. Not a return figure.
- Hit frequency. The share of spins with any win at all. Says nothing about the size.
All four are in the paytable or the information panel and readable without an account. What the terms mean individually is in the glossary.
What “unusual” can mean for a slot
What is unusual is not return figures but builds. The Supermeter mode in Mega Joker, where wins move into a second area with its own payout logic, is a genuine example. The Jokerizer mode in Jokerizer is another. Both are described in the paytable.
Not unusual but simply false are claims like “pays better at night” or “responds to stake size” — on which see the piece on design and the placing of the mechanics.
Which build suits whom
Classic titles with few lines suit a small budget and a fixed playing time: dry spells are shorter and the balance lasts longer. Titles with a progressive jackpot usually carry a lower base return, because part of every stake feeds the jackpot.
How that choice plays out over a longer period is shown by the 30-day calculation; the older generation of the same motifs is compared in the look back at 2012 to 2018. Bonus offers tied to such titles are converted into an expected amount on the bonuses page.
