Special symbols
WILD substitutes for every paying symbol above. A full reel of wilds locks that reel and respins the rest for free.
DIALDIAL lands on reels 1, 3 and 5. Land all three to crack the vault wheel. Pays nothing on its own.
PIGGY carries a cash value scaled to your bet. Land 6 or more to trigger the Lockdown. Pays nothing in a line.
The Lockdown
Land 6 or more golden Piggy Banks and the bank goes into lockdown. You get 3 respins. Every empty cell rolls; every new piggy that catches locks in and resets respins to 3. Lock 10 piggies and you break through to Floor 2, the Manager's Office, where the piggies get richer and you gain a respin. Lock 18 and you reach Floor 3, the Vault Floor, richest of all. At the end every piggy is counted up one by one. Fill all 30 positions for the Grand at 5,000x.
The Shakedown
Jade piggies are Shakedowns. The moment one lands, Mr. Long shakes down the whole board: every locked piggy pays its value over again. Then it locks in like the rest.
The Dial
The vault door above the reels is the combination dial. Each DIAL symbol that lands lights a lamp on the rim. Three lamps lock the screen and the dial spins where it stands. Segments hold free spins, instant cash, the Lockdown, ladder prizes, the Deposit Box Job and the Inner Vault. Inner Vault strips the low segments and respins, juiced.
The Deposit Box Job
Three deposit boxes from Mr. Long's private wall. Pick one, the crew turns the lock, the door swings. Inside is instant cash, free spins or the Lockdown.
Free Spins and Dynamite
The crew plants Dynamite that sticks to the board, fuse burning one stage per spin. When it blows it leaves a sticky WILD scorched into the board for the rest of the bonus, and wilds expand down their reel. Piggies still count: 6 or more fires the Lockdown inside your free spins. 3 dials retrigger +5 spins.

One thing is for sale: Spin the Dial, at 100x your bet. Everything else in this bank has to be hit the honest way.
