Tim Miller, who resigned from the UK Gambling Commission earlier this year, has stepped down from the GREF board and has relinquished his role as treasurer.
Miller served on the forum for several years and was a key UK figure during a period when the Gambling Commission implemented extensive reforms to online gambling regulation and affordability checks. GREF expressed its gratitude for Miller’s contributions during his tenure.
Jean-Michel Costes has also left the board after concluding his role at France’s Autorité Nationale des Jeux (ANJ).

Piggy Dynasty is built on a compact 3×3 layout with 5 paylines, and it puts the focus on smooth gameplay with frequent win potential. That structure signals a studio that prioritizes quick, repeatable spins over sprawling reel setups. It’s a design choice that suits shorter mobile sessions, where players tend to want fast rounds rather than a slow build toward a single bonus.
The game is backed by a solid mathematical model, with a Return to Player (RTP) of 96.01%. That figure sits within the standard band for mainstream slots. In other words, this is steady core content rather than a high-volatility outlier.
The central hook is how PopOK layers a multiplier system onto such a small grid. A fourth reel applies multipliers ranging from 1x to 15x, increasing the value of connected wins.
