Zombie Carnival

Zombie Carnival is a 6-reel, 4,096-ways slot from Pragmatic Play set in a zombie circus tent. 96.50% RTP (with 95.50% and 94.50% operator variants), very high volatility (5/5), 5,000x maximum win. The probability of hitting the maximum win is stated at approximately 1 in 3,300,000 spins — a figure PP has disclosed publicly, which is rarer than most studios provide.

The free-spin round triggers on 2 or more Brain scatter symbols landing anywhere on the reels, awarding 6 spins. The entry requirement is low — two scatters — which makes trigger frequency higher than most 5/5-volatility slots. During the bonus, each scatter that lands converts into a sticky wild and simultaneously increments a running multiplier by 1x. The multiplier applies to all wins in the round and carries across the entire bonus rather than resetting per spin, meaning each sticky wild that lands makes every subsequent win in that bonus heavier.

The Bonus Buy is priced at 80x the total bet, giving direct access to the free-spin round. The sticky-wild multiplier structure is directly comparable to The Dog House Megaways: wilds that persist and a rising multiplier funded by additional wild landings. Zombie Carnival uses a flat 4,096-ways 6-reel grid rather than variable Megaways heights, giving more predictable reel coverage per spin but less maximum-win capacity.

The mechanics are honest: the sticky-wild-plus-multiplier model is well-understood, the 2-scatter trigger lowers the wait time relative to 3-scatter peers, and the disclosed 1-in-3.3M max-win probability sets realistic expectations. The zombie-circus aesthetic is the most distinctive visual execution of the sticky-wild model in the PP catalog — not a selling point for every player, but it makes for a memorable session look.

Verdict
Sticky wilds, accumulating multiplier, low scatter threshold, 5,000x ceiling. One of the more transparent sticky-wild slots in the catalog.
