It may be that the casino you were looking for that game in just doesn’t have it. Not all real money online casinos have old-school games. Look for Playtech or Novomatic casinos if you want that vintage feel. It also may just be that this exact game is unavailable online, as it wasn’t remade. In some cases, a similar game is available for play, like in the case of Columbus and Columbus Deluxe, the latter one being available online.
