HippoPop Online Slot Review

Fluorescent zebras, flamingoes, and lizards are among the other-worldly stars of the HippoPop online slot. It’s another entry in the massively successful PopWins range, where symbols split on wins to create extra ways to line them up.

You can build up to 15,552 ways across the 5 reels, for some potentially huge payouts. Hit this target and you trigger free games, where an ever-increasing multiplier can boost prizes to a maximum of 48,150x your wager. HippoPop is a desktop and mobile game with high volatility and average returns of 96.1%. You can meet these abstract animals at the top New Jersey online casinos or the best Pennsylvania online casinos carrying the Yggdrasil range.

How to Play the HippoPop Slot Machine

Like the other PopWins games, such as TikiPop and BountyPop, this slot was developed in conjunction with AvatarUX Studios. The reels sit within a dense jungle, and a lively tune adds an extra dimension to the HippoPop slots game.

It’s definitely one of the slot games with a more impressive setting, and the symbols on the reels are equally eye-catching. Glowing card symbols feature on the 5x3 grid, along with the various animals. These crystal-style, glowing creatures also include fish, parrots, a tiger, and the highest-value golden hippo.

Gold-rimmed controls sit to the side, or at the bottom if you play on an Android, iOS, or Windows mobile. You can quickly and easily use arrow tabs to select a wager level, with options going from 0.20 to 40.00 for each spin. The double arrows in a circle activate Auto mode, and the 3 lines on the control panel unlock a paytable.

You win whenever 3 or more matched symbols land on connected reels from either the left or right sides. The hippo helps you to wallow in winnings by paying 1x, 2x, or 4x your wager when it lands on 3, 4, or all 5 reels.

The PopWins mechanism comes into play on any win. All symbols in a win ‘pop’ and they are replaced by 2 symbols, one above the other. This increases the reel height and improves your chances that another win is created. Any new symbols in a win also pop, and so on, until no new combinations are formed. During the base games, you can expand the reels to a maximum of 6 symbols high to give you 15,552 ways to win.

Free Spins & Other Bonus Features of the HippoPop Slots Game

Once all reels expand to 6 rows high, the HippoPop slot gets even more exciting. A multiplier increases by 1x for any further wins in the same series of pops. Once the sequence ends with a non-winning spin, you enter a free games bonus feature, with the current multiplier carried over. You get 5 spins by default, with an option to spin a gamble wheel for up to 12 extra games, but be careful, as you could lose the lot.

At the start of the free spins feature, the reels revert to 3 rows high, and PopWins steadily increase the number of rows on any win. The difference from the base games is that reels don’t reset back to 3 rows at the end of a series of PopWins and remain expanded until the next win, when they start to grow again.

You can build reels up to 8 rows in the free games, to give you 65,536 winning ways. Fully expanded reels also add 2 extra spins to your total.

Maximum Wins, RTP, & Volatility of the HippoPop Slot

Fully expanded reels filled with hippos pay 48,150x the total wager, or a massive 1,926,000.00 if you have 40.00 on the spin that triggers the bonus games. HippoPop is a high volatility game and the average return to players percentage is 96.1%.

Our HippoPop Slot Machine Rating

The PopWins mechanism is a thrilling innovation from AvatarUX and when you combine it with stylish animal symbols, you have a recipe for success. The average payback percentage is OK, but not exceptional, and the maximum wager of 40.00 could be a little low for some, but these aside, HippoPop is an outstanding game.

The expanding reels can lead to big wins, and once the free spins start, you are almost certain to land some decent payouts, even if you get just the basic 5 bonus games.
