Shelly Alon has lobbed off the price of his Silver Award-winning party-themed puzzle game Partyrs for a limited time.

Yep, it's completely free to download right now. If you grab it, you'll save yourself £1.49 / $1.99, which is the game's full price.

If you don't know, this is a game in which you must ensure everyone who attends your wild party is satisfied.

This involves moving them around the room so that they're stood next to the object of their desire. This might be a cat, beer, food, or music.

Making the puzzle solving more delightful is the range of guests that attend. There are robots, aliens, and animals stood on their hind legs having a good time.

Our reviewer said that it's a "game that hooks you casually and effortlessly, yet delivers on everything that makes casual puzzle titles the staple diet of the happy iPhone gamer."

You can grab Partyrs for free on the App Store right now. It's also available on Android but it's full price on Google Play still.
