Gold Bar is designed to expand the gameplay and proven award card structure of previous high stake games with the addition of a bonus 'award card switch' feature. The game is presented with 3 award cards which progressively increase in value. These award cards are represented by 3 colours : bronze, silver and gold. These colours are overprinted on certain reel band fruits.
When 3 identical colours appear in the 27-way win position, the game switches to the award card represented by that colour. This award card remains active until 3 different colours spin onto the reels, resulting in the card switching to the next colour.
