Where's My Water? 2 is a massive free-to-play Swampy sequel

We're approaching the 2-year anniversary of hydro-centric iOS puzzler Where's My Water?, and Disney is celebrating the occasion with a huge free-to-play sequel.

It's called, appropriately enough, Where's My Water? 2.

The gameplay is exactly the same as the gameplay in the first game. Swampy the Alligator needs water for his shower, but his suds are trapped behind six feet of dirt. So, you'll forge tunnels with your finger to direct the water back to Swampy.

New to this sequel, however, are the Duck Rush levels. In these endless-runner-style levels, the camera automatically pans down and you've got to quickly dig dirt and solve short puzzles to recover all six ducks.

Plus, every classic level comes with challenges. These might involve your turning the whole stage upside down, or your trying to finish the level without touching the ducks, and so on.

All 100-odd levels are presented on a single map screen. You can play levels from Swampy, Cranky, and Allie (those last two were previously paid DLC in Where's My Water?) from this one menu.

Where's My Water? 2 is a free-to-play game, so you can expect your progress to be stymied at every opportunity, and to be offered a number of in-app purchases to make your life easier.

The game sports an energy system, where you can only play a handful of levels before you're asked to wait, pay (at 69p / 99c a pop), or bug your Facebook friends until you can continue playing.

There's also a £11.99 / $16.99 in-app purchase available if you want to make the energy bar a little longer. And you can also buy hints and power-ups (which make it easier to collect ducks).

Where's My Water? 2 is available now as a Universal app for iPhone and iPad. It's free.
