In the early days of online casino gaming, 3-reels classic slots were the norm. Some titles drew immense traffic. But when the 5-reels video slots took over, these games began to fade away. Microgaming has revived these slot machines by converting them to the 5-reels format. Cool Buck and Bar Bar Black Sheep are being reviewed here. You can play these at Microgaming online casinos like 32Red, Royal Vegas and Spin Palace.

Green, the colour of money, pervades the screen in Cool Buck 5 Reels. The slot machine has the standard 5x3 structure with 9 fixed paylines. The Cool Buck logo is the wild symbol that appears super stacked on reels 3 and 4. It also awards the highest line payouts. The other high paying symbols are $ sign, cash and triple bar. The low paying symbols are brightly coloured playing card icons from A to 9. The rolled up dollar bill is the scatter symbol and awards payouts multiplied by the total bet.

Sometimes the playing card symbols will display a star. The stars get collected in a counter. The free spins can trigger in two ways. The first trigger is landing three or more scatter symbols on the reels. The number of free spins awarded is equal to the number of stars collected. The second trigger is collecting 30 stars. During the free spins all payouts are doubled during the free spins. Also the wild symbol appears super stacked on all the reels.

Bar Bar Black Sheep refers to the well-known children’s rhyme. You will hear the jingle of the rhyme as the game loads. The game logo is the wild symbol and also awards the highest line payouts. The other high line payouts are awarded by the black sheep, white sheep, barn and bar symbols. The low paying symbols are melon, apple, orange, brinjal and corn. The bag of wool is the scatter symbol and awards payouts multiplied by the total bet.

Microgaming has introduced an innovative bonus feature that is based on the name of the video slot. It is triggered when you land two bar symbols followed by the black sheep symbol in a straight row and in adjacent reels. Wild substitutions will not count for the trigger. The three symbols turn into a mini slot, with each reel containing numbers up to 9. The number displayed multiplies the line bet to give your bonus award. The scatter symbol triggers up to 20 free spins. All payouts are tripled except those arising from the Bar Bar Black Sheep bonus feature.
