PopRocks Online Slot Machine – Free Play & Review

PopRocks is not the type of game that will focus on its theme or on telling stories. It’s going to have very good graphics even so, since the attention to detail has always been great in Yggdrasil slots, but the symbols we see will provide us with a combination of colorful Royals and various gemstones which seem to have some kind of dragons incorporated into them.


Yggdrasil Gaming hails from Sweden, and it’s one of those smaller developers that appear to focus heavily on quality, so they don’t release a lot of slot machines.

The ones that they do release, will typically have excellent graphics, and as you can see in PopRocks, there are also cool features included, often enough.

How To Play It

With games that have regular lines, you often need to take into account the number of coins and their denominations, but that tends to change for the slots with ways to win. You just pick the total bet for the upcoming spin, that’s it. You have a minimum bet of $0.10, and a maximum one of $30.

Starting out with 486 ways to win, and advancing to as many as 33,614 ways, the mechanics of PopRocks are not the typical ones, and so learning how everything works might take a bit, especially for the features that don’t trigger immediately. You’re only required to spin the reels though, so actually playing the slot is not going to be difficult.

Special Features

PopRocks is one of the games that we’re seeing from Yggdrasil, and it’s going to innovate more than the typical slots that come from them. A new game mechanic is implemented inside, called PopWins.

PopWins is a different take on an existing system, and it takes cascading reels and uses them to bring the player 2 new symbols, for every 1 symbol that is removed. The game area expands on the reels which were part of winning combinations, so often enough only the first three columns will do that. Up to 7 symbols can be made available on each reel, and the number of ways to win will get a boost as well. The most you can have, is 33,614 ways to win, with all 5 reels expanded to 7 symbols each.

If that wasn’t enough, then there is also a multiplier which goes up, whenever symbols are popped, as a result of the cascading reels mechanic. For every 7 symbols that are involved, you get an increase of the multiplier, by 1x.

To trigger the bonus mode, you need the reels to all be expanded to their maximum size, with 7 symbols each. You get wilds as well then,

Maximum Payouts

Yggdrasil didn’t just create a new mechanic here, they also made sure that it will have awesome potential, and that’s exactly what we’re seeing in PopRocks. One of the biggest returns around is available inside, with 72,188x the stake being the highest that this game will go. The cap on its payouts is at $866,256, which the game can pay in a single spin.

The volatility can only be very high for a game with that kind of jackpot, but seeing as the RTP is set to 96.80%, I’m actually quite happy with how much it can pay on average.


PopRocks is an excellent choice, a game with a new game mechanic, one of the biggest top jackpots available in any slot machine, and a Return to Player that works well in combination with it, even as the volatility is very high.
