Money Train 4 at Royal Reels 25 — Relax Gaming, 150,000x

Six reels, six rows, scatter pays. Six or more matching symbols anywhere on the grid pays out. The base game is set in a steampunk western town, and the four highest-paying characters form the bounty hunter crew:

• Bronzo (gunslinger): 0.4x–1x for 6–36+
• Butch (sniper): 0.4x–1x
• Snowfall (axe thrower): 0.5x–1.25x
• Tombstone (dynamite thrower): 0.6x–1.5x
• Wreath (the sheriff): 1x–2x for 6–36+
• Payne (leader): 1.25x–2.5x

The base game pays out often (hit rate around 27%) but most base wins are tiny. The real money is the Money Cart bonus, which triggers when three or more bonus symbols land on the same paid spin.

Three bonus symbols trigger the Money Cart bonus. The three triggering symbols lock in place, the remaining 33 positions spin individually, and every new bonus symbol that lands locks and triggers a re-spin. Re-spins reset to 3 every time a new symbol lands. The round ends when three consecutive spins land no new symbols.

Every symbol that lands is a modifier. The simplest ones are money symbols with a value equal to the bet multiplier (1x–10x your stake). The complex ones modify other symbols, multiply values, add spins, or trigger respins on the entire grid.

How the round ends: 3 consecutive spins with no new symbol = round over. The running total of all symbol values is paid out at the end. With 12+ symbols locked and a stack of the right modifiers, the running total can clear 100,000x. The 150,000x cap is the absolute ceiling.

Every symbol in the Money Cart is a modifier. The full set:

• Money symbol: Value 1x–10x stake, paid at round end
• Collector: Collects values from all visible symbols and adds them to its own
• Payer: Adds its value to every other visible symbol, then pays out
• Collector-Payer: Collects from others, then pays its own value back to them
• Sniper: Doubles the value of 3–8 random symbols (up to 11 times per round)
• Necromancer: Revives 1–6 used dead bonus symbols and triggers a re-spin
• Absolver: Resets Collector, Payer and Sniper symbols to base value, then re-triggers their effects. Stacks with itself
• Tommy Gun Sniper: Adds its value to 3–5 random symbols 1–6 times
• Permanent Collector: Collects the value of every new symbol that lands for the rest of the round
• Permanent Payer: Pays its value to every new symbol for the rest of the round
• Unlocker: Unlocks an extra row on the grid (up to 7 rows total)
• Sleepy: Adds 1 re-spin, doesn't contribute value

The four permanent symbols (Persistent Collector, Persistent Payer, Tommy Gun Sniper, Necromancer) are what build the huge wins. A grid with three permanent collectors and a stack of payer symbols compounds the running total on every new symbol landing.

Relax publishes 96.10% RTP, 150,000x max win, ultra-high volatility. Royal Reels lists the game at AU$0.10 minimum, AU$10 max bet. Hit rate around 27% in the base game. Bonus trigger frequency sits around once every 250–300 spins on average.

The base game's hit rate is decent for an ultra-high-vol slot. You'll get a steady trickle of small wins (0.1x–0.5x) to keep balance ticking. The bonus is the gamble. Most bonuses pay 10x–80x. The 1,000x+ hits show up every few hundred rounds. The 10,000x+ hits are the ones that hit the community screenshot threads. The 150,000x ceiling is theoretical. It's been hit but not often.

Money Train 4 is part of Relax's Dream Drop jackpot network on some operators, but not at Royal Reels. The Royal Reels version is the standard non-jackpot build. The Dream Drop version has a lower base game RTP (94%) to fund the jackpot pool.

Money Train 4 sits in Relax Gaming's section of the lobby. Demo mode is open without an account. Real-money play needs a login and an AU$10 minimum deposit.

The game counts 100% toward bonus wagering on the welcome bonus and reload promos. The Buy Feature (75x–100x stake, depending on the spin) is available where local regulations allow. Most AU players skip the buy and trigger the bonus naturally. The base game hit rate is high enough that the bonus lands often.

Royal Reels's mobile build handles Money Train 4 cleanly. The grid is 6x6, so the symbols are slightly smaller than the standard 5x3 layout, but the Money Cart bonus reads fine on a 6.1-inch iPhone screen. Spin, bet, autoplay and the buy feature all stay thumb-reachable.
