The four fastest-paced machines
At the top of the list are the machines where the bonus feature triggers and pays out in relatively few steps. Wild Wild Chest belongs in this Football-Studio-level simplicity group, where the treasure-chest choice delivers a result within a round or two — the manufacturer-stated RTP is 95.71%, checked on 2026-09-22.
Big City Bank also falls into the faster category: the collection mechanic may take more spins, but every single step produces a result worth noting on its own, not just at the end of the bonus phase. Its RTP, per the manufacturer, is 95.94%.
Golden Fish Tank moves in a similar way: the fish collection is continuous, producing small, steady wins rather than concentrating the whole payout at the end of one big bonus round. The manufacturer states an RTP of 96.20% for this title.
Vikings Go Berzerk rounds out this foursome: its character-based features trigger relatively often, resulting in denser, shorter bonus phases. According to the manufacturer, RTP is 96.10%.
The four slower-building, longer-round machines
The second half of the list gathers titles where the bonus round builds over several stages, with the bigger payout typically arriving later, toward the end of the round. Dynamite Riches falls into this group: the chain of explosions gradually widens the win field, and the longer the bonus round runs, the bigger the final result can be. The manufacturer-stated RTP is 95.87%.
Dragon's Luck works on a similar principle, with a stacking payline system that expands round by round — RTP is 96.32% per the manufacturer, the highest value across the whole eight-title list.
Valley of the Gods, with its pyramid-shaped, descending grid, also rewards patience: symbols move gradually downward, and bigger combinations often only come together after several steps. Its RTP is 96.30%, according to the manufacturer.
Rise of Olympus closes the list: the cluster system and the divine multipliers pay out more slowly, but in bigger hits. RTP, per the manufacturer, is also 96.30%, matching Valley of the Gods.
Which pace suits whom
If you want to play out a round or two in a short break, the fast-paced foursome — Wild Wild Chest, Big City Bank, Golden Fish Tank, Vikings Go Berzerk — is the more convenient choice. Their bonus phase doesn't drag on unnecessarily.
If you're after longer, more leisurely rounds and don't mind a bonus round unfolding across several stages, the second foursome — Dynamite Riches, Dragon's Luck, Valley of the Gods, Rise of Olympus — will suit your pace better.
This isn't a strict rule, of course, just a general tendency based on how the eight machines are built. Individual preference matters too.
It's also worth factoring in that pace and RTP are two different things. A fast-paced machine doesn't necessarily pay less over the long run — its payouts simply arrive more often, in smaller portions, while the gradually building machines pay less often but in bigger chunks. If you plan to play with a given budget for longer, this distinction is worth weighing alongside theme choice.
