Piggy Bankin'
A technical and mathematical review of the Piggy Bankin' family — WMS's 1996 coin bank and Big Bang Piggy Bankin', the portal bonus of 2008–2014, Lock It Link Piggy Bankin' and its SuperLock Jackpot, Light & Wonder's Break In and Piggy N' More Bankin', and the online Super Lock — the coin bank priced from the only numbers ever published, every bet on the record reconciled to its game, New Jersey's jackpot lists read in full, and the family's true persistent state separated from the pigs that only look full.
Executive summary
One name has covered four different games for thirty years. Piggy Bankin' began as a Williams three-reel slot in 1996, came back as WMS's networked bonus in 2008–2014, returned under the Lock It Link name from 2017 when Scientific Games owned the brand, and in 2025–2026 became Light & Wonder's Break In and Piggy N' More Bankin' and an online game; what the four generations share is the pig and the registration, not the mathematics. The record holds fourteen products under the name (Table 6.1).
The 1996 game had a real bank, and the maker's own patent fixes how it worked. A WMS patent filed in 2001 describes the earlier game's "bonus accumulator in the form of a piggy bank": every spin of three blanks adds the wager to the bank, and a "Break the Bank" symbol on the third reel pays it all; the collector page that says three such symbols were needed is contradicted by it. The bank reset to 10 coins, paid in full to a one-coin bettor and was hunted by players who called it a "vulture" game; no maker or trade source dates the original, and its 1996 date rests on collector pages.
Priced from the only published numbers, the bank's 10-coin seed was worth 5.56 points more to one-coin players than to two-coin players. A practitioner's 2013 figures — a break once in 90 spins, three blanks once in 11 and an 18-coin cost to play a bank off — make the 10-coin seed worth 11.11% of one-coin play but 5.56% of two-coin play, and the blank feed 9.09% at either; on his own valuation a bank was worth its size less 18 coins, so his 40-coin bank was worth 22, and nothing published ties the 1-in-90 chance of a break to the bank's size. At one coin a bank of 40 or more stood on 3.1% of cycles; at two coins, on 17.7%.
A nine-bank WMS game held the family's one trigger that had to come. In the game Know Your Slots describes, filed with the portal generation by inference, one "lucky coin" sits among 510; it must be reached by the 510th coin, and with three banks left — about 170 coins if the banks are equal — the expected coins to the trigger fall from 255.5 to 85.5.11 The coins a wild drops are not published, so the countdown cannot be priced in dollars.
Lock It Link Piggy Bankin' is a 50-line, 500-credit game whose Grand can fall on a minimum bet. Every bet on the record that names a denomination — $5 and $25 at 10¢, $50 and $500 at $1, $250 at the inferred 50¢ — is a multiple of 50 credits, one to ten a line; players report Grands on $5 bets at Harrah's New Orleans and the Flamingo, and a player who read the help screen reports that the jackpot chance rises with the bet. Station Casinos priced its 2019 SuperLock bank from $0.60 to $30, and the SuperLock Piggy Bankin' bets in players' titles, $6 to $30, fall inside that range.
New Jersey's lists, read in full, hold 42 Lock It Link Piggy Bankin' jackpots totaling $4,708,316.29. Ten of them name only Piggy Bankin'. They run from December 8, 2018 to July 4, 2026, peak at $199,315.89 at Hard Rock on March 7, 2021, and fall into two groups: 25 awards from $100,000.00 to $199,315.89 (median $143,831.43), at 10¢, $1 and multidenomination machines alike, and 17 from $44,007.07 to $94,000.00.19,20,21 Break In's first row is $58,179.25 at Borgata on May 29, 2026. The list prints denomination, never the bet.
Break In is a 40-line, 800-credit game with a 25¢ high-limit base and three bonus pots. Light & Wonder calls it "The first follow up title" to the brand and a trade magazine "the first new Piggy Bankin' title in 10 years"; both are wrong on the record, which holds three Australian Piggy Bankin' approvals of 2017–2018, the SuperLock build and Piggy N' More Bankin', announced five weeks before Break In was listed. The chief executive put it at #1 among new video reel games in Eilers' index on debut and called it a core franchise in August 2026.
The maker publishes two sets of returns, and neither is for an American casino floor. The online Super Lock comes in four versions, 96%, 94%, 92% and 90%; New Zealand's Piggy N' More Bankin' cut sheet prints four returns from 88.49% to 91.99%, a fixed $500 Grand and a $300 Major that grows at 0.20% to a $500 ceiling with a 0.90% reset rate. If the reset rate is the $300 start times the Major's hit rate, as its label suggests though the sheet does not define it, the Major comes once per $33,333 wagered — once in 13,333 games at $2.50 if its chance is proportional to the bet — and averages $366.67, or $363.35 if growth stops at the $500 ceiling (Appendix B).
Bad figures attach to the family from 1996 to 2026. A register names nineteen: the collector page's three symbols, 1996 date for Big Bang and lawsuit; a guide that calls the 1996 game a Light & Wonder hold-and-spin; the maker's "first follow up"; a transcript's "Piggybacking Break"; and affiliate pages that give the online game a 96.02% return, 3, 10 or 50 lines and jackpots that are fixed, progressive and absent at once.
The family runs in seven channels, and the rules on displays that build differ by country. Land Class III, tribal sales under a 1999 license, Australian approvals, New Zealand's Class 4 market, Class II from 2026, real-money online outside New Jersey and SciPlay's social apps all carry the name; GLI-11 requires a persistence game to explain its thresholds in the help screens, Australia and New Zealand forbid a display that only seems to build, and Nevada barred "Due," "Overdue" and "Ready to Hit" in February 2026.
Two of the family's pig displays stored state between players. The 1996 coin bank was true persistent state that carried value, with nothing published to tie its timing to its size; the nine-bank game's piggies were true state, bounded at 510 coins; the Lock It Link pigs live only inside the feature; and what Break In's pots do between bonuses is not published. no Light & Wonder copy read labels a Piggy Bankin' display "perceived persistence," though the company uses the phrase for a Huff N' Puff hat (Appendix C).
What the volume covers
Section 1 is the orientation: four generations under one name, and the companies behind them. Here a generation is a game design the name was put on; a build is one approved configuration of it; a bank is a display that holds coins or credits; and a pot is Light & Wonder's term for a display that upgrades a bonus. Section 2 is the dated record, from the Telnaes case to the 2026 trademark filings; Section 3 the cabinets; Section 4 the rules of every generation; Section 5 the mathematics — what is published, the coin bank priced, the countdown, the bets and a register of bad figures; Section 6 the census. Sections 7 to 10 cover the jackpots and New Jersey's record, the bet structures, the market and the law. Appendix A grades the sources, Appendix B shows every calculation, and Appendix C classifies every display that looks like progress. SIS 26-PB · Piggy Bankin'
