The announcement

Galaxy Gaming and Spirit Gaming announced the deployment of 36 Galaxy Operating System progressives across eight Merkur casino locations in Germany. The September 2025 release identifies 21+3 and Heads Up Hold’em among the featured brands.

What it covers

The named locations include Hohensyburg, Duisburg, Bad Oeynhausen, Monheim and Aachen. For blackjack readers, 21+3 is the relevant side-bet connection; the rollout is not evidence that all table games at those venues use identical rules.
