Like many slots online, the coins sizes start at a quarter, and carry on up to $5. The max win on this machine is 2,500 coins, or at top coin size, $12,500.

The Diamond Sevens machine is part of the microgaming network of online slot machines, and can be found at many of the microgaming casinos, including The Lucky Nugget.

If you enjoy the three reel, one payline, three coin format, then you really do have a large number of slots games to choose from. Bar Bar Black Sheep is one of these games, powered by Microgaming. The theme is clever,a play on the familliar children's rhyme, Baa Baa Black Sheep. It features cunning sheep, bags of wool and of course, black bars. Every family has a black sheep, he's here too.

The paytable appears right on the screen with the reels, which means there's no switching back and forth between screens, or searching and studying to find the payout combinations. In addition to being conveniently displayed, the combinations are pretty straightforward. You're looking for bags of wool and bars. Even the bars are simple, with just double and single bars.

The black sheep is not only wild for all characters, but it is also a multiplier. When it appears as a part of a winning combo, it multiplies your win by three. The only exception to this rule is that it does not triple the payout on the jackpot winning line. That line, by the way, is Bar-Bar-BlackSheep. How cute.

At the casino we chose to check this game out, the coin size was variable from .20 to $5. Should you be lucky enough to spin the winning jackpot line, you'll have two bars and a black sheep. The payout on the jackpot, when all three coins are bet is 1600… This translates to $8,000 with the max coin size. Compare this to $2,500 jackpot when one $5.00 coin is bet. When one coin is bet the payout is only 500, making it an advantage to be the maximum bet. In other words, the payout increases at a rate greater than the bet when betting the maximum amount. $8,000 is more than three times $2,500.

Bar Bar BlackSheep can be played at Roxy Palace.

Another of the three coin Microgaming games is Chief's Magic. The game has three reels, one payline and a three coin maximum. The theme is based on an Indian Chief but the sounds and graphics aren't over the top by any means.

The focus of this game is very straight forward. With a 600 coin maximum payout, you might think you'd want to pass this one up, but where we played, the coin was variable in size from .25 to $10. Whith such a wide variation, this game becomes a very flexible fit for all players and all wallets.

No matter what your budget, it definately pays to play the maximum number of coins, even if you can't afford the largest coin. The payout on three coins is greater than three to one on one coin. Your best bet is to first decide on the bet you are comfortable making. Then divide by three and set yoru coin size to that size. Then, with each spin, bet three coins. Let's be honest, there's not a whole lot of strategy involved in slots, but this is one way you can improve your payout when you do win.

With no bonus or wild symbol, you are free to concentrate on the elements of luck that are at the core of slot machine gambling. No gimmicks and gizmos to distract you, this game is straight forward and enjoyable.

This traditional 3 Coin slot takes coins that range in size between 25¢ and $5. That means each spin will cost 75¢ on the low end, or as much as $15 for the high rollers.
