Mining pokies aren't exactly rare. Kiwis have been watching gold carts, dynamite and bearded prospectors roll across the reels for years, so when CT Interactive released yet another one in February 2026, my honest first reaction was "right, here we go again". Then I read the bonus rules. They're stranger than they look at first glance, and that's mostly what this guide is about.
The full name is Happy Miner: Riches of the Mine, and it went live on 1 February 2026. Nothing wild on paper:

Mine Shaft Bonus and a Gamble feature |
One thing missing from that table is RTP. The developer's game page doesn't show it, and published figures range from roughly 95.7% at the low end to 96.6% at the top. That usually means the studio ships several versions and each market gets one of them. The info panel inside the game at LevelUp shows exactly which version applies to your account, so check it there before assuming anything.
The symbol set is pretty much what you'd guess. A shovel, a pickaxe, a stick of dynamite, a lantern and a mine wagon make up the regular pays. Above them sit the two that matter:
• the Miner Wild, which substitutes for regular symbols to complete lines
• the Golden Nugget Scatter, which lands anywhere and opens the bonus
The art is cartoonish, bright, a bit cheeky. CT Interactive's chief product officer Dimitar Ivanov described the game as "built around the timeless appeal of classic slots", and yeah, that's fair. It doesn't pretend to be anything it isn't.
Three, four or five Golden Nugget scatters trigger the Mine Shaft Bonus. And here's the part that made me read the rules twice: you start with 0, 10 or 20 free games depending on the scatter count.
Zero. With three scatters you walk into the bonus with no free spins at all.
That sounds like a bad joke, but it isn't, because the bonus isn't really a free spins round with a few decorations. It's a pick-and-climb feature where the free games are one of the things you earn along the way.
The feature has four levels. On each one you pick from a set of Golden Nuggets, and each pick can unlock a Wild Reel (a full column of wilds for the spins), a multiplier on wins, or additional free games.
When the bonus ends, the game pays 5x your total bet on top of any extra free games you collected. So even a quiet run through the mine returns something. Not a fortune, but not nothing either.
Because of that structure, a three-scatter entry still gives you four rounds of picks. If the nuggets are kind, you can climb from zero spins to a decent set with a wild reel attached. If they aren't... well, you get the 5x and move on. The five-scatter start with 20 games is obviously the dream, but it'll be rare. With volatility rated 4 of 5, expect long stretches of small or no wins between features. That's the trade.
CT Interactive keeps its classic gamble option here. After a win you can risk it on a guess to double it, or just collect. It's optional and personally I'd leave it alone most of the time. It doubles the swings on a game that already swings plenty.
What works:
• Four-level bonus with real choices, not just a spin counter
• A guaranteed 5x total-bet payout at the end of the feature
• 10,000x ceiling is high for a plain 20-line game
• Clean, simple base game that runs well on phones
What to keep in mind:
• RTP depends on the market version, so it varies
• High-ish volatility means dry patches
• Three-scatter bonuses can feel thin when the picks go badly
• Fixed 20 lines won't impress anyone chasing Megaways-style mechanics
Worth mentioning, because the NZ rules shifted this year. The Online Casino Gambling Bill got Royal Assent on 27 April 2026 and the Act came into force on 1 May. Up to 15 operator approvals are being handed out by the Department of Internal Affairs, and from 1 December 2026 operators that haven't applied have to stop taking New Zealand players.
For the average Kiwi punter this mostly means one thing: the game itself won't change, but the rules around who can serve NZ accounts will settle over the next year. Keep an eye on the DIA's published list as December approaches, the way you'd check any official register.
With a bonus this layered, a few dozen demo spins tell you more than any guide can, mine included. If you want to see the rules panel and the nugget picks for yourself, the casino page for the happy miner slot has both a free demo and a real-money mode, and the demo runs without an account.
A last honest note. It's a high-volatility game, and the 10,000x figure is a ceiling, not a target. Set a limit in your LevelUp account before you start, treat any spend as the cost of entertainment, and if gambling stops feeling like fun, the Gambling Helpline NZ is free on 0800 654 655.
