Pop

Pop by Big Time Gaming is a 4-reel, 4-row video slot with 256 fixed ways to win that takes place on a boardwalk pier atmosphere, complete with Ferris wheels, seaside lights, and carnival flair. The symbols are split between low-paying royal cards and high-value coloured balloons in red, blue, green, and purple. A “Reactions” mechanic ensures that when symbols form winning combinations they pop and are removed, making way for balloons, scatters, or Wilds to float upwards to fill the gaps, possibly triggering further wins in the same spin. Wild symbols appear on reels 2-4 only, and when they contribute to a win they can reveal hidden multipliers up to ×4. Scatters (gold coins bearing the Big Time Gaming logo) land or are bounced onto the reels, and landing three or more of them launches the Free Spins feature. Free Spins begin with 12 spins and all 16 positions on the grid have their own multipliers which start at various levels: some begin at ×1, others at ×2, ×3, or ×4 depending on how the Free Spins were triggered. Throughout Free Spins, winning balloon or Wild symbols on any position increase that position’s multiplier, and landing three or more Scatters during Free Spins grants three extra spins and boosts one of the multipliers by one level. There is also a Bonus Buy feature, allowing the player to immediately purchase the Free Spins round (typically 12 Free Spins) by paying a set multiple of the stake. Pop has high volatility and offers a maximum win potential of up to 66,960× the bet.
