User description: PLONK is a new rules system for Vihan Lapset RPG. Due to criticism toward diceless FLOW-system originally used in Vihan Lapset, the developers decided to publish an alternative rules system using six sided dice. The PLONK-system is still under development and this version 0.1 is the first published version. It is given out for free from the publisher's booth at conventions for players who have bought Vihan Lapset. The system is meant for Vihan Lapset RPG, but the rules themselves are not tied to the game, so it could be used as an universal system for any RPG.
