Wow. I really like this. It's hard to make something different in this genre but they managed. The previous review gave a wonderful description, so I am not going to repeat it all the details. I do think the 'story' is silly. And I found the colors difficult to distinguish - such as the white and grey. It is difficult, but you do catch on after awhile. Numbers get crossed off as you color the squares, but if you hover the mouse over them the 'X' will disappear. I do wish they had not done that. You must try this before buy and persevere - don't try a couple of screens and give up. I suggest you do try the tutorial. Basic rule of thumb.... Numbers of the same color will have 1 or more space between them. Numbers of different colors may or may not have a space between them. For the 10x10 grids, if the numbers add up to 10 just pit them in the grid! You can right click to X out a square - just be careful. Have Fun!!
This game uses 3 different colors for each grid, but handles the switching between colors differently than anything I've seen before. I found this new way pretty hard during the one hour demo, where the grids were only 10x10. The grid has all the colors listed above the columns and beside the rows. All the tiles that must be turned are in the numbers, with the color of the number telling you which color you need to use. The rule that at least one blank tile must be between two numbers still applies, but only if the numbers next to each other are the same color. But if the next number is a different color, there may or may not be a blank tile between it and the previous tile. Kind of hard to explain, but I found it a lot harder to figure out which tiles needed to be turned and which color needed to be used. As usual, if the numbers add up to the total number of tiles for that row/column, then it's a piece of cake. But you have to remember that numbers next to each other with different colors don't necessary have to have a blank tile in between. In other multi-colored grids I've played, when you count the numbers you include a blank tile between the numbers. For instance, a row with the numbers 1-2-1-3 on a 10 tile row would fill up the row with 7 tiles turned and 3 blank. The same row of numbers in this game 1 red, 2 green, 1 white, 3 red would also mean that 7 tiles need to be turned, but you have no hint as to where the blank tiles fit, because numbers with different colors do not necessarily need a blank tile between them. Only if two numbers are the same color are you required to place one or more blank tiles between them. So given the same numbers but changing the colors would produce a different count; 1 red, 2 red, 1 white and 3 red means there are still 7 tiles to be turned and there is at least 1 blank tile between the two consecutive red numbers. That leaves 2 blank tiles that could be anywhere. Takes some getting used to and some brain power to solve the grids, but this new challenge really makes the game fun.
