At the start of the Hold & Win bonus, all Wild Piggy symbols transform into House symbols that correspond to them. If the Hold & Win bonus is triggered by golden coins, House symbols are added to the reels until there are between 6 and 8. The Hold & Win bonus is guaranteed to trigger if 6 or more Wild Piggy symbols land in the same spin.

The Hold & Win bonus starts with 3 free spins. Each time a House or Booster symbol lands on the reels, the free spins are reset to 3. During the Hold & Win feature, only House, Booster, and Empty symbols can land on the reels.

During the Hold & Win bonus, all House symbols that land on the reels are locked and remain until the end of the feature. Up to 4 House symbols can land on the reels per spin. When there are no free spins left, each House symbol receives a Cash Prize depending on its type. The House symbols are:
Straw House symbol - Straw Cash prize or Mini Jackpot prize
Wood House symbol - Wood Cash prize or Minor Jackpot prize
Brick House symbol - Any Jackpot prize

If 15 symbols are locked on the reels, the feature is terminated.

When the game is launched for the first time, the values of some of the Cash and Jackpot Prizes are boosted as follows:

• 1x Cash Prize is boosted by +1x

• 3x Cash Prize is boosted by +2x

• 7x Cash Prize is boosted by +8x

• 10x Cash Prize is boosted by +20x

• The Mini Jackpot Prize is boosted by +50x

• The Major Jackpot Prize is boosted by +500x

• The Grand Jackpot Prize is boosted by +1500x

There are 5 Jackpots in the game. They are:

• Mini Jackpot - 25x Prize, grows +5x, up to a maximum of 75x

• Minor Jackpot - 50x Prize, grows +5x, up to a maximum of 150x

• Major Jackpot - 250x Prize, grows +25x, up to a maximum of 750x

• Mega Jackpot - 500x Prize, grows + 50x, up to a maximum of 1500x

• Grand Jackpot - 1000x Prize, grows + 100x, up to a maximum of 5000x

When a Booster symbol lands on the reels, it upgrades the value of up to 3 Cash or Jackpot Prizes. Straw Cash Prizes are upgraded by +1x, Wood Cash Prizes are upgraded by +2x. Winning a boosted Prize resets it to its base value.

Only one Booster symbol can land on the reels per spin.

There are Cash Prizes grouped by material around the reels. The straw Cash Prizes have values of 1x, 2x, 3x, 4x, and Mini Jackpot. Each straw Cash Prize can grow up to a maximum of double its base value. The wood Cash Prizes have values of 5x, 7x, 8x, 10x, and Minor Jackpot. Each wood Cash Prize can grow up to a maximum of triple its base value. The growth of the jackpots is separate from the Cash Prizes.

If the Cash and Jackpot prize values are too big to display, they are instead displayed as bet multipliers. The values of the Cash and Jackpot Prizes are saved throughout play sessions for the game at the bet settings.

There are 3 Wild Piggy symbols that substitute all other symbols except Boost symbols. The Wild symbols are:
- Straw Farmer Piggy, up to 6 per spin
- Woodworker Piggy - up to 5 per spin, apply a x2 multiplier to all Win Lines they participate in
- Builder Piggy - up to 3 per spin, apply a x3 multiplier to all Win Lines they participate in

When multiple Wild Piggy symbols participate in a Win Line, their multipliers are added together.

When a Piggy Wild symbol lands on the reels, it throws golden coins equal to its multiplier to the pile above the slot. Each golden coin has a chance to trigger the Hold & Win bonus. The graphical accumulation of coins is purely for entertainment purposes and does not influence the chance for triggering of the feature.

All symbols pay from left to right on the defined paylines.
