The vault is the wild symbol and it will substitute for all of the other symbols, except for the scatter symbol, to help and form winning combinations.
The scatter symbol is the game’s logo and it is key to one of the bonus features.
The slot offers a Feature Bet Mode. You can improve the potential payouts by upgrading symbols. If you click on the ‘Feature Bet’ button then you can choose your feature bet level. You can upgrade four of the symbols and your bet will increase proportionately for each one that you upgrade.
- Upgrade level 1 costs 1.5 times your stake and makes the watch worth up to 58.33 times your bet.
- Upgrade level 2 costs 2 times your stake and makes the sports car worth up to 62.50 times your bet.
- Upgrade level 3 costs 2.5 times your bet and makes the female spy worth up to 70 times your bet.
- Upgrade level 4 costs 3 times your bet and makes the male spy worth up to up to 83.33 times your bet.
The free spins begin when you land the scatter symbol on reels one, three and five simultaneously. You win 10 free spins during which the paylines become bidirectional. In other words, you can land winning combinations from left to right starting from the leftmost reel and from right to left starting from the rightmost reel. Any symbols that you have upgraded will remain so in the free spins but the spins cannot be retriggered.
On any spin, a reel can turn into a Red Reel. If you land 3 or 4 Red Reels then you will win 3 or 25 times your bet, but if all five reels turn red then the progressive jackpot is yours. The wild symbol and the male spy are the most valuable symbols and can payout up to 50 times your bet. The female spy can payout up to 35 times your bet, the sports car can payout up to 25 times your bet and the watch can payout up to 17.5 times your bet. The ₿ and $ can payout up to 6 times the bet, and the remaining currency symbols can payout up to 3 times your bet.
