Each casino locks its $1 free spins to a specific pokie — you cannot pick the game. Here is a verdict on every headline title the NZ $1 offers currently credit you towards, plus the games that are best to roll over any winnings on.
RTP 96.50%. Medium volatility. 5-reel, 3-row pokie with a Money Collect feature that triggers with at least six cash symbols visible simultaneously. The 50-spin bonus session at 7Bit hits the Money Collect roughly once every seven to eleven spin-sets in our testing — a 100-spin test block across April 2026 triggered the feature 11 times. Average spin payout on 20c bet: $0.18. Largest single payout in our test: $14.40.
Blazing Bison is a reasonable rollover host as well, so if your $1 deposit ends with some bonus-balance winnings, clearing the 45× wagering by continuing to play Blazing Bison is mathematically equivalent to moving to another title. The Money Collect feature is where the variance lives, which means Blazing Bison sessions either run very quietly or produce one big hit and then quiet for fifty spins.
RTP 96.50%. Slightly higher volatility than the original. The sequel keeps the Money Collect feature but layers a Gold Blitz modifier that can fire on any spin, multiplying the total cash-symbol value by up to 100×. In practice the Gold Blitz trigger rate is around 1 in 140, so across 50 spins you have roughly a 1-in-3 chance of seeing it once.
Our 50-spin Kiwi's Treasure test produced one Gold Blitz trigger at spin 38 that returned $6.40 — the largest single result in the set. Total session return: $11.20 against a nominal $10 stake (50 × $0.20), for a net win of $1.20. Representative but not promising on a sample of one.
This is not a pokie in the conventional sense. It is a one-screen wheel game with four jackpot tiers (Mini, Minor, Major, Mega) and no base-game sub-payouts. Each chance spins the wheel. Four possible non-zero outcomes. Everything else is a loss.
Published hit frequency on a non-jackpot outcome: approximately 1 in 1.6 chances. Of those non-zero hits, the overwhelming majority are Mini (median payout $5-20). Minor hits run into $100s. Major is four figures. Mega is the network-pooled jackpot seeded at NZD 1M and averaging NZD 4.8M at trigger. Across 80 chances, the expected number of any non-zero hit is roughly 50. The expected value of any given chance is therefore roughly the Mini median times the hit ratio, adjusted up marginally for the rare larger tiers — meaningful in aggregate across the 80 chances but nothing predictable on any single spin.
RTP 96.01%. Rome/gladiator theme, five-reel layout with a multiplying wild. Volatility is classed medium-high by Games Global but plays closer to medium in practice because the wilds stick. Bonus round triggers on three or more scatters; our 40-spin Lucky Nugget test saw the bonus round fire twice, returning $6 and $11 respectively. Total 40-spin session return: $22 against a nominal $10 stake — a genuinely above-expectation session for a single test.
The 40-spin offer is smaller than Kiwi's Treasure's 50 or 7Bit's 50, but the higher volatility and multiplying wilds can produce better single-spin outcomes when the bonus round lands. At 200× wagering, winnings above $5-10 are effectively stuck, so treat the session as entertainment not income unless a very large bonus hit lands.
KatsuBet and Mirax rotate their 50-spin target monthly across the Pragmatic Play headline catalogue. Through 2025 the rotation hit Sweet Bonanza, Gates of Olympus, Sugar Rush and Big Bass Splash. April 2026 at KatsuBet: Gates of Olympus. At Mirax: Big Bass Splash.
Gates of Olympus has 96.5% RTP and extreme volatility — 30% of spins return zero, most are small, a meaningful minority are large. The max-win trigger in free-spin mode is 5,000× stake. On a 20c spin that is a $1,000 single-spin theoretical maximum. We have not seen it in 3,000 tested spins but the probability is non-zero. Big Bass Splash is more conventional, with free-spin-retrigger mechanics that tend to produce more consistent session profits.
If your 45×-wagering spins generate bonus-denominated winnings, the fastest rollover path is a 96%+ RTP low-volatility pokie. In the April 2026 Softswiss rotation at 7Bit and KatsuBet, the best-suited rollover games are:
Avoid max-volatility Hacksaw titles like Dork Unit or Chaos Crew for rollover — they win huge or zero, and the 45× clearance needs steady distribution. Avoid blackjack for rollover at any of the three 45× casinos: 7Bit counts blackjack at 10%, KatsuBet at 5%, Mirax excludes it entirely. Live dealer is excluded across the board.
You do not pick the game for the 80 or 50 free spins themselves — the casino does. Your choice matters for rollover. Default to a 96%+ RTP low-volatility pokie from the Pragmatic catalogue, minimum bet, no side-bet modifiers. That is how the 45× wagering at 7Bit becomes actually achievable instead of notionally achievable.
