Included in a highly successful series from Yggdrasil Gaming and AvatarUX, HippoPop relies on the PopWins mechanic once again, and while it changes some things, overall it’s going to be a familiar slot experience. One of the things which has changed, the wildlife theme is designed more as a way to get inspiration from those creatures, and doesn’t show them in their real form.

HippoPop offers 5x3 reels with 243 ways to, which will pay both ways (hence the claim that 486 ways are available). Expanding via the PopWins, the slot’s game area can eventually have up to 65,536 ways active, at least for a little while. Thanks to its huge game area, but also with help from special features, it’s possible to get wins of up to 48,150x the stake here ($1,936,000 is the maximum win), while the RTP is 96.10%. Special features will include the PopWins mechanic, cascades, multipliers and free spins.

Betting and Prizes

You go for the regular total bet as you start playing this, where 20 coins are used to allow for bets of $0.20 to $40.

HippoPop is actually quite impressive as a game with high volatility, being capable of turning a $40 bet into a $1,926,000 prize. That’s a 48,150x the stake return, way above the average even for the most volatile online slots.

Despite the risk involved, long-term it all evens out, since the RTP is 96.10%, which is considered standard. It’s something that no individual player will see though, since this is likely going to be a wild ride, with many downs and few ups.

The hit frequency is on the low side as well, at 20.5%, so about 1 in 5 rounds will bring you a win.

HippoPop Slot Features

You start playing this game on 5x3 reels, where 243 ways to win are present. Since the game pays both ways, meaning left to right and right to left, it’s said to be a slot with 486 ways.

From there, you will be looking to get wins formed, with 3+ symbols appearing on consecutive reels. Once that happens, the PopWins mechanic kicks in, and splits the winning symbols into 2 positions. As the winning reels have more symbols now, the number of ways to win will expand. You can go from 5x3 reels to 5x8 reels, and eventually have up to 65,536 ways active. The game area resets back to 5x3 at the end of the round.

Until the round is over though, you keep benefiting from cascades, where winning symbols get removed, and the new wins can form additional combinations. It even gets more likely for that to happen, since there are more symbols which could be part of a combo now.

Once you reach the maximum game area size, rather than get additional positions, you get a higher multiplier. It goes up by 1x for each cascade, and it also resets at the end of the spin.

Another advantage, is that Hippo symbols become more valuable as you take the game’s reels to a bigger size. You need to unlock all of them at 6, 7 or 8 symbols high, before you can get wins worth 2x, 3x or 4x the usual amount.

To activate the free spins, you need to unlock all reels during a single paid spin. A bonus wheel spins, to decide how many free spins you get, and it looks like you could have anywhere between 5 and 14 rounds in total.

In this mode, you will be using the reels at their standard size, but with the same option to expand up to 5x8 reels, where you would get 65,536 ways to win. You also use the multiplier from the triggering spin, as a starting point. It will increase by 1x after each new cascade. Between spins, the game area will reset only partially, to the size of the smallest reel, but the multiplier goes only up.

Theme & Design

They decided on a common theme, with wild animals from Africa shown on its reels, and with a jungle filled with flowers and vegetation in the background. The implementation is not the standard one though, and all those creatures used as top symbols look like they were made out of precious gems, and cut to the expected form.

You’re still going to discover a number of Royals (J-A) in the bottom positions, but the top and medium ones will include images which look like Hippos, Flamingos, Panthers, Zebras, Frogs, Parrots and Fish.


HippoPop is going to be a fun experience for anyone that loved the PopWins series, and it will bring more of the same great features, large top payouts, and a style of gameplay which is going to feel different from what you get in most competitors.
