How to play Rat King
The more distinctive layer is the game’s use of 2×2 colossal symbols and a Battle feature, in which colossal and Wild symbols land to cover a Battle symbol after a non-winning spin. These additions don’t reinvent NetEnt’s math. They extend the cascade model with bigger blocks and a triggered mini-sequence, keeping the release familiar to players who know the studio’s earlier Avalanche games.
NetEnt also attaches its Elevate suite of paid bonus-entry and feature-boost options
NetEnt also attaches its Elevate suite of paid bonus-entry and feature-boost options. That reflects the wider industry move toward giving players direct routes into bonus play rather than waiting for natural triggers.
About Rat King
This isn’t the first time this policy has been mooted in the Dutch parliament. A 2025 bill proposed raising the age for “higher-risk” activities like online slots.
Van Bruggen insisted more time was needed to establish whether an age limit hike to 21 would actually have the adverse effect of pushing young people in the Netherlands towards unlicensed offerings.
Among those pushing for the increased age limit were the SGP’s Diederik van Dijk and the CDA’s Tijs van den Brink.
What is Rat King?
Researchers conducted a rapid desk review of 53 relevant sources, three deliberative focus groups segmented by gambling product type (sports betting, online casino/slots and land-based gambling) and four in-depth interviews with people identified as being at higher risk of harm (Problem Gambling Severity Index (PGSI) score of 8 or more).
A total of 22 participants were purposely recruited to provide detailed insights.
Participants broadly accepted the principle that gambling information should be transparent and accessible, but many reported difficulty interpreting or using it effectively in practice.
