Where's My Water? is a charming physics puzzler, in which you funnel clean water to the bathtub of a fastidious little alligator named Swampy.

Where's My Water? ranks among the better arcade puzzlers, sharing some similarities (fast-paced levels, an intuitive interface, and a winningly cartoony protagonist) but with a central schtick that's mostly all its own: you dig paths through dirt, creating channels for liquid to flow from one place to another. Ideally, you'll get enough clean water into a pipe to fill Swampy's tub, but along the way you have to contend with various … Read more

For instance, last year's Limbo not only won the hearts of gamers and critics alike, but took the 9 spot in our annual top 10 games of the year list.

This year's Summer of Arcade has already hit the ground running, starting off with last week's addictive action-RPG, Bastion. We demoed the game live on CNET TV's preGame show.… Read more
