Math Game - Regrid

Regrid is a game of math skills based on the resolution of mathematical expressions easier.The game is played on a grid of 4 x 4 cells.Each cell of the 16 provided may contain a number from 1 to 9 or any of the mathematical operators (+, -, /, *)The grid contains 8 numbers and 8 operators randomly mixed.The aim of the game is to get the result (GOAL) which in turn is proposed.There are 4 tiers of increasing difficulty (KIDS, EASY, HALF, HARD).The sublevels can play without order of priority: it is not necessary to solve them all to move to the next level.For example, if you solve the KIDS sublayer of the first level you get the release of the second level where you can play any of the four sublevels.Have Fun!Update 11 / 07 / 2014- Some levels seem impossible to solve, and then we were asked to implement a help. For each level Easy, Half and Hard is now possible to get the first and the last cell of the expression.
