Six casinos in Poland have joined up to offer a progressive Mega Jackpot slots prize.
Casinos Poland venues, which are found in hotels across the country, are the gambling arenas taking part in the collaboration.
According to Century Casinos, a US firm that has a 33.3 per cent stake in Casinos Poland, this system means that gambling enthusiasts can see their potential prize increasing as they play.
"Via the progressive jackpot system, a part of every bet made on slot machines connected to the network is accumulated into a common pool," the company said in a statement.
Two casinos in capital city Warsaw and one each in Wroclaw, Krakow, Poznan and Katowice are where the slots game can be accessed and played.
Last month, Century Casinos announced that a Casinos Poland venue had opened at the Marriott Hotel in Poland's capital. A special launch party was held to mark the occasion.
