The symbols simply land over the background of the alien planet. In the base game, they are 25 on 5 reels and 5 rows.

These are all kinds of aliens with 1, 2 or 3 eyes each, aerials and they have unique shapes and colours. There are pink, yellow, blue, turquoise, orange and in rainbow hues aliens. Their total number is 8 and each one has its own face expression – angry, joyful, happy or other.

Besides the 8 different aliens, in the game can land light-green oracle wild symbols. There are flaming planets as scatters. The Monster Cloner planets have pink “G” marking on each. The free spins play in an orange and fiery alien planet. The soundtrack during them is more joyful and funky.

The soundtrack in the base game is mysterious, electronic and rhythmic. It mixes with the sounds of symbols dropping on the screen and wins as well as the triggering of features. The game is cute, colourful, innovative and very pleasant.

Monster Pop Gameplay

Monster Pop uses cluster pays mechanism of rewarding. The regular paying symbols are 8 different aliens. They have different colours, face expressions, 1 2 or 3 eyes and shape and may have aerials. They all pay the same and have equal value. Your payouts depend on the number of matching symbols that form a cluster.

You win when you match 4 or more adjacently positioned symbols. they must touch horizontally or vertically. This makes them explode and pop new ones on the free spaces from above, while the rest of the symbols drop down. You can score new wins from the cascade and the process repeats. Each win triggers a cascade which activates more as long as new wins occur.

Clusters of 4 adjacently matching symbols horizontally or vertically pay 1.60 times your stake. Clusters of 5 symbols – 2.40x stake, 6 in a cluster – 3.60. If you hit 7 symbols in a cluster, you win 4.80x stake, 8 to 10 symbols give you from 10 to 12 times your stake. Clusters of 11 to 13 symbols pay 16x stake, 14 to 16 symbols – 24x stake, 17 to 20 symbols grant 32 times your stake. If you land 21 to 25 symbols of a kind you will win 40 times your stake, 26 to 30 symbols clusters – 60x stake.

Getting between 31 and 35 symbols of the same type give you 80 times your stake. Clusters of 36 to 40 symbols give you 100 times your stake. Clusters of 41 to 45 symbols grant 120 times your stake, 46 to 50 symbols – 140x stake, 51 to 60 symbols – 160x stake. Get between 61 and 80 identical symbols to win 200 times your stake, from 81 to 100 symbols – 280 times your bet. The largest clusters of between 101 and 1,000 symbols ensure you 400 times your stake win. This is the largest payout of clusters and it is quite abundant.

The green Oracle Eye symbol with the “W” inside is a wild. It substitutes for all regular symbols except Monster Cloners and scatters.

Monster Pop Features & Bonuses

The game starts at 5×5 layout with 5 reels and 5 symbols per reel, thus including 25 symbols. Every time you land the Monster Cloner special symbols – the grey planet with pink “G” on it, this expands the grid. This happens with 1 reel (vertically), 1 row (horizontally) or both 1 reel and 1 rows. The latter is the most beneficial for the player.

The added extra reel/row is the same on which the Monster Cloner landed so, it gets duplicated. On the place of the Monster Cloner symbol in the duplicated row/reel is added a Wild Oracle Eye. This gives you more chances to win. The grid will continue to expand with each landed Monster Cloner symbol. More of them give you a larger expansion. The fully expanded grid can contain up 13 reels and 13 rows. It resets after each new spin in the base game but stays expanded during free spins.

Another feature which is part of the gameplay in the slot is the Monster Fury. It triggers randomly after a cascade with no wins. The monsters can get angry on your behalf. They can create a Cloner Bomb that spread Monster Cloners around the grid. The monster can shuffle themselves within the grid. Identical monster symbols can group together and ensure you more wins. If they award you with extra Monster Cloner symbols, the grid will expand for each such symbol.

Landing 3 Flaming Sphere symbols, which are the scatters, in a spin sequence gives you 7 default Free Spins. You get one more free round for each landed scatter added to them. The more scatters landed per spin sequence, the more free spins you will get. The ratio is as follows:

  • 3 scatters’ trigger – 7 default free spins + 3 more = 10 total free spins
  • 4 scatters’ trigger – 7 default free spins + 4 more = 11 total free spins
  • 5 scatters’ trigger – 7 default free spins + 5 more = 12 total free spins
  • 6 scatters’ trigger – 7 default free spins + 6 more = 13 total free spins
  • 7 scatters’ trigger – 7 default free spins + 7 more = 14 total free spins
  • 8 scatters’ trigger – 7 default free spins + 8 more = 15 total free spins
  • 9 scatters’ trigger – 7 default free spins + 9 more = 16 total free spins
  • 10 scatters’ trigger – 7 default free spins + 10 more = 17 total free spins

Free spins start at the default 5×5 grid. During these rounds, the grid expansion occurred from the Monster Cloner or Monster Fury is kept. It doesn’t reset the grid. You will play with the same bet size as the one that triggered the bonus game. During free spins, you have the best chances to pocket massive wins.

These can ensure you amusing rounds. The volatility is on the medium level so, players with all bankrolls can have fun with the slot.
