Piggy Thief

A 97.0% RTP, a Bank Robbery feature where safe symbols lock into expanding blocks, and four fixed jackpots give Piggy Thief a distinct identity inside Onlyplay's jackpot slot catalog. The 5x3 grid runs 50 paylines with medium volatility and a 39.42% hit frequency, making the base game one of the more active experiences in the portfolio. Free spins award 10, 15, or 20 spins depending on how many Scatters trigger them. Six or more Safe-deposit box symbols during the bonus open the dedicated Bank Robbery round where the jackpots resolve. Available at Wild.io with full crypto support on desktop and mobile.

What is Piggy Thief?

Piggy Thief is a 5x3 video slot from Onlyplay with a 97.0% RTP, medium volatility, 50 paylines, and a 39.42% hit frequency. It runs a standard free spins mode triggered by Scatters and a dedicated Bank Robbery feature activated by 6 or more Safe-deposit box symbols, which awards four fixed jackpots: Mini, Minor, Major, and Grand.

The standout mechanic is the Bank Robbery feature, which operates as a separate bonus state from the free spins round. During the robbery, only box symbols appear on the reels. Each one that lands locks into place, and boxes can merge into larger blocks as more accumulate. The bigger the merged block, the larger the associated win. The jackpots resolve at the end of the robbery sequence, and the four-tier system runs Mini through Grand. The 97.0% RTP is notably high for a jackpot slot, sitting above most peers in the hold-and-win category.

Piggy Thief Slot Theme & Graphics

Piggy Thief uses a heist narrative built around a cartoon pig protagonist pulling a bank robbery. The 5x3 grid features themed symbols drawn from the heist concept: safes, coins, and character symbols that fit the cartoon-crime aesthetic Onlyplay uses across several of its pig-themed titles. The tone is light and cartoonish rather than realistic, which keeps the theme accessible.

The Bank Robbery feature is where the theme fully expresses itself. The visual shift to a safe-only reel set during the robbery sequence, with boxes locking and merging on screen, ties the mechanic directly to the narrative. The pig heist mascot character appears throughout the game's animations, and the audio design uses heist-adjacent music cues. On mobile the 5x3 grid reads cleanly at smaller sizes, and the jackpot resolution at the end of the Bank Robbery sequence has enough animation weight to make the jackpot reveal feel distinct from a standard scatter win.

Piggy Thief Slot Symbols & Paytables

Piggy Thief has a straightforward 5x3 paying symbol set alongside a dedicated bonus symbol (the Safe-deposit box) that only becomes the primary reel content during the Bank Robbery feature. Understanding the role of each symbol type clarifies when each bonus mode becomes active.

Low Value Symbols

The lower-value symbols in Piggy Thief are the standard coin and playing-card-style icons styled in the heist aesthetic. These appear most frequently across the 50 paylines and contribute to the 39.42% base-game hit rate. With 50 paylines on a 5x3 grid, even low-value symbol combinations resolve frequently, which is what makes the base game session feel active. These symbols do not play a role in the Bank Robbery feature, which has its own dedicated reel composition.

High Value Symbols

The high-value symbols are the thematic premium icons: character symbols representing the pig thief and associated heist props. These produce the largest standard payline wins in the base game. A full 5-symbol combination of the top-paying symbol across a payline is the peak single-spin payout available outside the bonus features. During free spins, high-value symbol wins stack against whatever run of spins the free spins counter provides, making them more impactful over the 10-20 spin range.

Special Symbols

Wild symbols substitute for all standard paying symbols and help complete payline combinations. Scatter symbols trigger the free spins round: 3 for 10 spins, 4 for 15, and 5 for 20. The Safe-deposit box symbol is the gateway to the Bank Robbery feature. During the bonus, 6 or more box symbols landing activates the dedicated robbery round where the standard reel set disappears and only box symbols appear. These boxes lock into place as they land, merge with adjacent boxes into larger blocks (with larger blocks paying more), and at the end of the sequence the jackpot tiers resolve. The four jackpots are Mini, Minor, Major, and Grand.

Piggy Thief Bonus Feature & Special Features

Free Spins

The free spins feature in Piggy Thief triggers when 3, 4, or 5 Scatter symbols land on the 5x3 grid. Three Scatters award 10 spins, four Scatters give 15, and five Scatters produce 20. The free spins run on the same reel set as the base game, so all 50 paylines remain active and the standard symbol values apply. What makes the free spins phase significant is that Safe-deposit box symbols can still appear during the bonus, and 6 or more boxes triggering the Bank Robbery from within the free spins creates a path to the jackpot tiers within an already-active bonus state. Free spins can also retrigger, giving another set of spins if further Scatters land during the bonus.

Bank Robbery Feature

The Bank Robbery feature is the centerpiece of Piggy Thief. It activates when 6 or more Safe-deposit box symbols land during the bonus phase. Once triggered, the standard reel symbols are replaced entirely by box symbols. Every box that lands locks into place immediately, a hold-and-win structure where each new box resets the spin counter back to three remaining spins. When two or more boxes occupy adjacent positions they merge into a single larger block, and the monetary value of a merged block exceeds the sum of individual boxes. This block-merging mechanic is what creates the path to the higher jackpot tiers. When the respin counter reaches zero, the jackpot evaluation runs: the four tiers are Mini, Minor, Major, and Grand.

Bonus Buy

Piggy Thief includes a bonus buy option for players who want to skip the base game phase and access the bonus directly. The cost is a multiple of the current stake. This is useful for players targeting the Bank Robbery feature specifically, because the normal path requires landing Scatters for free spins and then 6+ box symbols within that bonus. Bonus buy eliminates the first gate, though the second (the box symbol density in the bonus) still applies naturally. Given the 97.0% RTP, Piggy Thief is one of the more mathematically favorable slots to use a bonus buy on, though high-volatility bonus features retain their inherent variance regardless.
