## What is Neiscat?

Neiscat is an original strategy game, where you will play against the iPhone/iPod touch.

The game was adapted from its original version on the HP-41 calculator.

There are only a small set of rules, but the possibilities for strategies are endless.

A new game starts with the number 3 in the middle of an hexagonal board.  The objective is to complete 1-2-3 series either vertically or diagonally.  You and the iPhone/iPod touch will play each in turn the numbers in the order 1-2-3-1-2-3...   The number completing a 1-2-3 series will be added to your score, hopefully a 3.  Once a number has been used to score a 1-2-3 series, it will be highlighted and neither player will be able to reuse it.

FEATURES
 - Addictive, you want to win. Come on, its a phone, how good can it really be?

### 4/5 — excellent strategy game, good computer opponent

*2008-12-06*

A well-made game. It has similarities to Tic-Tac-Toe, but with a more extended play and scoring. The trickiest part of the strategy is that you get more points for completing a series with a higher numbered piece. The computer whomped me the first time I played.

I knocked off a star because the tutorial could use some improvement, and the tutorial also crashed a number of times.
