Steam's seasonal sales are pretty legendary stuff, combining store-wide discounts with interactive challenges, special bundles, and limited edition virtual badges and trading cards for die-hard users to worry about collecting.

There are typically four each year: a Summer Sale, Halloween Sale, Autumn Sale (for Black Friday), and Winter Sale (for Christmas). They're fairly predictable, but exact dates are only revealed at short notice, which keeps us on our toes.

But in 2018, it looks as if Steam has thrown the rule book out of the window with a surprise Lunar New Year Sale. The latest online sale celebrates the year of the dog, and is live for the next few days.

If you're not a Steam fan, plenty of the Steam alternatives run their own rival discounts around similar times, so keep an eye on the likes of GOG.com and Green Man Gaming. And if you're looking for great discounts year round, you should take a look at our pick of the best gaming deals.

When is the Steam Lunar New Year Sale 2018?

The latest sale is the Steam Lunar New Year Sale, and true to Steam's reputation for keeping sale dates secret, nobody knew it was coming until a few days prior. We're happy to say that the sale is live right now, offering discounts on some of the biggest games of 2017 including Ark: Survival Evolved, Planet Coaster and Cuphead. 

The sale officially kicked off on 15 February 2018, and is set to go on for four days, until 19 February 2018. If you're ready to wave goodbye to your wallet, simply head over to the Steam Store's dedicated sale page to find the latest and greatest deals.
