Sam & Max Beyond Time and Space Ep 1 is going free on the App Store for a limited time.

If you've never stepped into the (gum)shoes of doggy detective Sam and his rambunctious rabbit sidekick Max, then Telltale has just given you the perfect excuse to put this pair of sleuths through their paces.

For absolutely no outlay whatsoever, you can point-and-click your way through the first episode of this surreal saga, which pits you against that holly jolly criminal Santa Claus.

What's more: if you take a shine to the crime-busting critters' puzzle-solving antics, you can pick up the remaining four episodes for £1.99 / $2.99 each (40 per cent off their usual price).

Of course, these offers won't last forever, so we suggest you act fast if you want to crack the first case without breaking the bank.
