Redtail Robber Cash Vault Heist is a Play'n GO video slot on a 5x4 grid with 20 paylines. The base game revolves around a Fox on reel 5 that collects Coins, and Mystery symbols that open into Cashpots. Coins can also trigger a Bonus Game played with lives, and Scatters start free spins.
Play'n GO lists the average RTP at 96.20%. Casinos can run lower RTP versions, so check the game's info screen before you play.
In the base game the Fox lands only on reel 5. It's a wild, and each time it lands it collects and pays the values of all the Coins on screen. It can also carry a 2x, 3x, 5x or 10x multiplier, or none. The multiplier applies to any line win the Fox is part of, and to Coin and Cashpot values.
Coins can land on any reel and show 0.2x, 0.4x, 0.6x, 0.8x, 1x, 2x or 5x the base bet. In the base game they never form line wins and only pay when a Fox collects them. Mystery symbols can land on any reel too, and each one reveals a Cashpot of 10x, 20x, 50x or 100x the base bet, which pays when the spin ends.
Any Coin can trigger the Bonus Game, and 6 Coins in one spin guarantee it. The round starts on an empty 5x4 grid where only Coins and Mystery symbols can land, and you get 3 lives. Each spin uses a life, every new Coin or Mystery symbol refills the lives to 3, and when they run out the round pays the combined value of everything that landed.
Scatters land only on reels 2, 3 and 4, and 3 of them start the free spins with 10 spins. A Fox is placed on the grid at the start and stays for the whole round. Between spins it moves to a new spot and gets a new random multiplier, and it collects any Coins that land. Every further 3 Scatters add 10 more spins, with a maximum of 100 free spins in total. If one spin triggers both the Bonus Game and free spins, the free spins follow once the Bonus Game ends.
The top win is 15,000x your total bet in regular bet and 10,000x in GO Ultra bet. That cap covers every win in one game cycle, features included. Play'n GO puts the chance of hitting it at 1 in 1,000,000,000.
GO Ultra bet is an optional extra 50% on your total bet, which you switch on or off in the base game. With it on, a Lucky Coin is added to the Bonus Game before the first spin and moves after every spin. Each move it either absorbs the symbols directly above, below, left and right of it and adds their values to its own, or doubles their values. No single symbol can go above 5,000x the base bet. That is a cap on one symbol, not the game's max win. Prizes are still worked out from the base bet, so the extra 50% doesn't make them bigger.
Volatility is high, according to independent slot trackers; Play'n GO doesn't publish it.
In Play'n GO's official demo, bets run from 0.10 to 50.00. Casinos set their own limits, so the range at your casino may be different.
