### **7not7**
### *A 7x7 clone written in java*
This page should be viewed on [Github](https://github.com/id101010/7not7)
---
### Summary
7x7 is a concentration game which challenges you to connect 4 or more blocks of the same color on the game field.
To make things harder each round n blocks of random colors get thrown upon the field and the number n increases with each level.
You can choose the field size to be eighter 7x7, 8x8, 9x9 or 10x10.
You can choose the field size to be either 7x7, 8x8, 9x9 or 10x10.

The goal is to clear as much lines as possible by stacking blocks of the same color in any direction.
So you can eighter build up blocks vertically, horizontally or diagonal.
To move blocks click on the block you want to move, hold the mouse and release it on the target position.
