Number Fisher
The title of this post reflects the name of the Android game my friend and former ACDSee Online teammate released not too long ago. Since I was among beta-testers of the game I wanted to help out spreading the word about this great app.
Numbers Fisher is a free brain puzzle that allows you to check and train your observation and memory skills. The goal of the game is to find the numbers (or letters) in order from least to greatest as quickly as possible.
Number Fisher is available on Google Play as well as has its own Facebook page.
Is this js based or native android?
It is native Android but there is HTML5 version at http://numbersfisher.com/.
