Dogs in slots are mostly the property of Pragmatic Play’s The Dog House, and the different editions of one idea show how the studio keeps developing a game. The original arrived on 9 May 2019: the classic 5×3 layout with 20 lines and very sharp maths, where every Wild on reels 2, 3 and 4 carries a multiplier and free spins grow through sticky Wilds. The Dog House is high volatility with 96.51% RTP and a x6750 cap. The closest edition is compared in The Dog House vs The Dog House Megaways.
The Megaways edition came out on 12 August 2020 with six reels, up to 117,649 ways and a choice of bonus. After free spins trigger, you decide between sticky Wilds and Wilds that drop randomly; the sticky mode has fewer spins but more potential, up to x12,305. It returns 96.55% at high volatility. The third variant, The Dog House Multihold, appeared on 27 February 2023 and works differently: free spins run on four boards at once and sticky multiplier Wilds hop from board to board. RTP is 96.06% and the cap x9000.
Two dogs of a different breed stand aside. Relax Gaming’s Top Dawg$, from 2 June 2021, is the studio’s most street-level game: a 5×3 field, 15 lines, Mystery Respins and Sticky Wild Free Spins in which sticky Wilds grow up to x7 and multiply together, with 96.10% RTP and x25,000. Hacksaw Gaming’s Le Fisherman arrived on 5 February 2026: a French bulldog named Smokey heads to the lake because rumour has treasure on the bottom, and the cap is x15,000.
All five rest on high volatility, which is the main thing that unites them. RTP differences are small, 96.06% to 96.55%, so choose by mechanics. Classic fans should start with the first The Dog House, those wanting room to roam with the Megaways edition, and anyone who likes seeing many boards at once with Multihold.
