Hi, I was totally lost in this game till my daughter showed me how to play.
Click a square hopefully more than 1 will disappear.
Try to find a pointed area that show a 1... click on the number 1 it should highlight blocks hopefully a crystal is showing too. If it highlights a showing crystal and other blocks, the crystal is found so the other blocks are all safe. If no crystal is found and it highlights 1 then thats the crystal..right click it ...keep clicking on the numbers showing... it will show you where the crystals are.
If one number doesn't work try the others around it.Like if you have a 3 and it shows 2 exposed crystals you know there is 1 more click on the numbers around it till it shows one block, thats the crystal.. once you have 3 showing any other blocks highlighted are safe...So easy to learn if you can be shown in person.
Any way click the actually numbers showing on the board. play with them you will see what I mean.
If you really get stuck and your scan is active use it.
If you click a number and all those crystals for that number are exposed then the highlighted blocks are safe.
It doesn't say anything in the How To about clicking the numbers but since I learned this I've blown up 1 crystal because i left clicked instead of right clicked.
I tried explaining this the best I could ...If you have question I will try to clarify it better.
Good luck to you all on the up coming challenge! :)
