This Dublin restaurant will give you FREE cocktails if you win a game of heads or tails

We'll be there all night.

There's nothing better than having a few tasty cocktails with the girls/your SO/just about anybody.

And while having just cocktails is all well and good, it's nice to throw in a bit of grub too.

Combine all that with a (potential) night of free booze and you're totally sorted.

Ruby's Pizza and Grill (who do the most delish chicken wings btw) are running a promotion at the moment and it sounds quite fun.

All you have to do is flip a coin - if it lands on heads, the restaurant will pay for your cocktail, and if it lands on tails, that means you have to pay.

It's currently cocktail week in Ruby's and the promotion runs until Thursday (March 8), so you better round up the girls quick if you want to get in on the fun.

Some of the cocktails include a Pornstar Martini, a Lemon Bon Bon, a Mojito and a Flirtini.

We looked up the probability of getting heads in a few rounds of flipping a coin... so, if you flip a coin four times, the Theory of Probability says: "If we assume that each individual coin is equally likely to come up heads or tails, then each of the above 16 outcomes to 4 flips is equally likely. Each occurs a fraction one out of 16 times, or each has a probability of 1/16."

We'll take our chances... and drink our cocktails either way.

Ruby's has locations in both The Point Square and the Pavillions Shopping Centre.
