Ante Bet is an on-screen switch that raises the cost of every spin and in return improves the chance of a bonus. Unlike a buy, it does not hand you the round: the triggering symbols still have to land, only they come around more often. Symbol payouts stay the same, and in most games the RTP does too.
The most transparent version is in BGaming’s Gemhalla (2023). The stake becomes 25% dearer, scatters are twice as likely by the studio’s description, and RTP stays at 97.17% in all three modes. A given bankroll buys a fifth fewer spins, but each one sits closer to a bonus, with no guarantees. In Pragmatic Play’s Gates of Aztec (31 January 2023) RTP is 96.50% in normal play, with the ante and on a buy. The ceiling in ante mode, according to demo data, is 4,000x against 5,000x.
Working out whether the surcharge pays
Wild Wild Riches (Pragmatic Play, 2020) hangs on one event: a pair of Wilds on reels one and two. The ante raises the odds of exactly that pair. The label promises double the chance. Taken literally, features per unit of money come out at 2 / 1.2, about 1.67 times as many, with a stake a fifth higher. On a small budget the trade is simple: bonuses more often, spins fewer.
The surcharge is far heavier in Push Gaming’s Razor Ways (2024): +300%. A thousand spins at a base bet of 1 cost 4,000 instead of 1,000, and expected loss at 96.36% RTP grows from 36.40 to 145.60 euros. The guaranteed effect is limited to two mystery symbols. In Relax Gaming’s Jurassic Party the ante is called Mega Bet: the buy rises 50%, from 80 to 120 bets, and RTP moves from 96.47% to 96.51%. The myth is that Mega Bet brings the 20,000x cap closer; the cap is measured on the regular bet.
Pragmatic Play’s Chilli Heat Megaways keeps 96.50% in every mode, whether you add the ante, buy the round or do neither.
