What's New


- 4 new Sparks with all new behaviors!
- A new rare Special Spark (1UP)
- Spark spawns have significantly more variety to them now!
- New High Score Leader Board specifically for v1.1
- New "longest chain" Leader Board
- OpenFeint Achievements! Earn OpenFeint Points!
- More sound effects (and improvements to some old ones)
- Backdrop "red shifts" as it speeds up
- Slightly modified the Slow Special Spark (slows a % now)
- Some bug fixes
- Smaller download size! Yup... we squeezed it!

This version adds a lot to the later game, for all you reaching for the big scores.

The new sparks provide a wicked twist on gameplay that you'll have to discover as you go.

The new 1UP Special Spark comes out rarely, but it gives you the ability to survive a clash and keep going!

We honed the gameplay even better this version through careful balancing of randomness with difficulty progression. This is particularly significant in games where you survive to see some of the new Spark behavior!

Get ready for geoSpark – a collaboration between the acclaimed developers of geoDefense and Harbor Master. It’s the fastest game on the App Store!

An assortment of colorful neon Sparks are flying across the screen, and it’s your job to prevent any two different Sparks from colliding. Chain similar Sparks together by dragging them with your finger. The more Sparks you eliminate at a time, the more points you get.

But be careful! As your chain gets longer, your finger becomes a gravity well that draws all nearby Sparks inwards, adding even more entropy to the mix.

Be on the lookout for bonus Sparks with special powers – they’re the key to mega success. See how high you can score, then brag to your friends via OpenFeint!

geoSpark: all the spectacle and style you expect from the geoDefense series, with the addictive, casual gameplay of Harbor Master.

Thanks from Critical Thought Games and Imangi Studios!
