Pop is a Big Time Gaming slot with a carnival-themed design, set on a 4-reel layout and 256 paylines. The game uses a high-volatility structure and an RTP of 96.54%, with wins paid from left to right and multiplied by the stake.
The reels feature colourful balloon symbols alongside classic card symbols, including A, K, Q, J, 10 and 9. The rules also highlight Wilds on reels 2 to 4, where a Wild can reveal a multiplier of up to x4 and substitute for most symbols, while Scatters remain separate from standard substitutions.
A key mechanic is the reaction feature: winning symbols can be replaced by a Scatter, Balloon symbol or Wild, which may create further wins in sequence. The demo version allows players to play for free and practice before playing for real money, while the paytable explains the symbol values and feature rules.
