Big Prosperity Spade Gaming: the Jackpot inside the Free Spins

The Big Prosperity Paytable opens with a section called How To Win Jackpot, so this guide starts there too: when the Jackpot can happen, how the Free Spins are set up with two picks, the dice game after a win, and what each symbol is worth. It is a 5 reel, 15 line slot. At BolehSpin, Big Prosperity opens from the Spade Gaming lobby (bolehspin.com/games/spade-gaming) in your phone browser. This H5 version needs no app download and no separate game ID; one BolehSpin account is enough, and the game plays straight from your BolehSpin main balance with nothing moved in or out.

A Jackpot that lives in the Free Spins

The How To Win Jackpot section and the Jackpot Feature section print the same short set of rules:

  • The Jackpot feature only occurs during the Free Spin Feature.
  • The Jackpot symbol only appears on reels 1, 2 and 3.
  • When 3 Jackpot symbols appear, the player may be awarded an available jackpot.
  • The jackpot that may be awarded is determined by the bet level.

Setting up the Free Spins: boxes first

3 or more η™Ό SCATTER symbols anywhere on the reels trigger the Free Game. At the start, players pick cards to reveal hidden numbers and keep picking until the Finish icon is revealed. The Paytable calls these the treasure box. The revealed numbers are added up and awarded as Free Spins; the Paytable prints 5 up to 20.

Then a gold ingot for the multiplier

With the spin count known, players choose 1 of 5 Gold Ingots (the Paytable says golden nugget) to reveal the bonus multiplier played during the Free Spins. The printed values are x2, x3, x4, x5 or x6. Additional Free Spins can be won during Free Games, and the Paytable says more free spins can be retriggered indefinitely.

GAMBLE GAME: Dice

After each winning combination, players may choose to gamble the win in a dice game:

  • Call small (1 to 3) or big (4 to 6); a correct call doubles all winnings.
  • Or guess the exact dice number for a x6 multiplier on all winnings.
  • The gamble can be played up to a maximum of 4 levels each time.

How a win is counted

Wins go to adjacent symbols from left to right on adjacent reels on an active payline, except SCATTER wins, which pay on any position. Only the highest symbol pay is awarded on the same line. The Help Page prints Line wins = Credit X the multiplier in the paytable, and SCATTER wins = Total Bet X the multiplier in the paytable; SCATTER wins are added to line wins. The WILD substitutes all symbols except SCATTER and appears randomly on any reel.

Settings and buttons

The bet is built from Value, Level and Credit, with the printed spin cost example 0.02 x 3 x 15 = 0.90. Total Bet can be picked directly on desktop only. Auto Play runs from 10 rounds up to infinity, and there is a fast spin button. The settings page has Exit, Speaker, Menu, Game Help, Replay, History and Expand. Malfunctions void all plays and pays.

Big Prosperity paytable

Values as printed on the Paytable page (Symbols Payout Values) for 5, 4, 3, 2 and 1 symbols. The SCATTER section prints All wins is multiplied by total bet, and 5, 4 or 3 SCATTER also give + Free Spin. Help Page: Line wins = Credit X multiplier; SCATTER wins = Total Bet X multiplier.
