Gridland is strange. It's familiar but strange. In a good way. It's also a free browser game that you should consider playing.
On the surface it's a typical match 3 game -- you know, like Candy Crush or Bejewelled -- but imagine if, instead of disappearing into thin air, those match 3 items became resources which you could then use.
That's the high concept of Gridland. You play match 3, but while the game is being played a character above the game is using the resources you create to build stuff -- houses, shelter, etc -- in order to protect himself from enemies that attack at night.
Yeah, I almost forgot. Gridland is a bloody match 3, strategy game with a day/night cycle.
And it grows in layers. As you progress through days and build more defences during the day, it enables you to use different weapons at night. It's pretty insane. I don't want to ruin the experience too much, just give it a try and head in with an open mind.
Gridland is just a very compelling experience that works in layers. It's extremely original and I recommend that you give it a bash immediately and wave bye bye to any sort of productivity.
