Piggy Bank: Coinstorm — slot review and demo

Bonus Coin and Collector Mechanics in Piggy Bank: Coinstorm

The slot is built on a 3×3 grid with 5 paylines. The core mechanic revolves around Bonus Coin symbols, which land only on the 1st and 3rd reels and carry random values: from 1x to 15x the bet or one of four jackpots (MINI, MINOR, MAJOR, GRAND). The Bonus Collector symbol appears exclusively on the 2nd reel—one per round in the base game, up to three simultaneously in the bonus game. The Collector gathers and sums all values from coins that landed with it.

There's a random event: if the Collector lands without coins and without winning combinations, it can transform random symbols on the 1st and 3rd reels into Bonus Coins and trigger the bonus game. The bonus game itself activates when coins land on the outer reels and the Collector in the centre. It starts with 3 spins; each new coin or Collector resets the counter back to 3. Random multipliers x1–x5 appear above the 1st and 3rd reels, changing with each spin and boosting coin values on the corresponding reel. Collectors collect the values and clear positions. The round ends when spins run out. For the impatient, there's a bonus buy option—direct purchase of the bonus game.

Specs and Payout Potential

RTP stands at 96.05%—a standard figure for video slots. Volatility is stated as medium, meaning a balance between payout frequency and size. Maximum win reaches €750,000—an impressive figure for a compact grid. Provider Evoplay is known for unconventional solutions, and here it shows in the coin-and-collector pairing. Other games from the studio can be found in the Evoplay slots catalogue.

Farm Theme and Golden Reserves

Visually, the slot is rendered in light tones with a farming backdrop: gold bars, coins, and piggy banks create an atmosphere of rural prosperity. The Coinstorm name lives up to itself—in the bonus game, coins truly rain down, especially if x4 or x5 multipliers linger above the reels.
