@Telestriation, From what I can see, it's based on individual levels and not total GFs made. I could be wrong since the only GF I got to unlock a secret so far is the one for the orange level. I refuse to go back and GF the ones I missed until later too, since there's so much left to unlock still for me.
@everyone, Does anyone know offhand what level you can get all skills? Also, has anyone made a level 11+ gem? I'd be interested in seeing the stats on those.
I'd say it's easily possible to get 7m on each of the secret levels.
Here's a helpful strategy tip. When combining equal level gems, drag the better gem (not vice versa). This means if you drag a level 1 gem onto a level 7, your new gem's stats get based off the level 1 :S Good luck winning with one of those!
Cast Mana Pool until you have 4920+ mana. Then on the last waves save the mana so when the boss comes you have your mana full. If the boss enters your tower while you have enough mana (4920), you will 'banish' him and he will have to do all his way again. Once he makes it through your towers for the second time, just throw your high-level gems at him to finish him off (if it's needed). Armor skill decreases the amount of mana needed for banishment, and More Initial and maximum mana makes it easier to get the size of mana pool big enough.
i tried starting a new game and re-running some combinations of levels between the 1st and 2nd boss. got the yellow secret levels 3 times, each time triggered when getting GF on a different level.
Looks like its based on getting GF on a number of levels within a given area.
no, it isn't the boss levels. they hack the high scores by using the cheat engine. it allows you to get to a higher skill level (say level 100000 instead of level 9) and a higher score per level with a similar method, as far as i know. There are some youtube vids on how to do it.
Managed to get the glowing frame on all levels up to the first epic battle (including that one too). So now on level 24.
However, no more battles seem to be available to me - are all greyed out. This is the sort of behaviour I'd usually expect with a message that says "if you pay a subscription fee the next levels will be unlocked". But nothing like that is happening.
The first hidden level is also visible (the awful one with only green gems available) which I just can't seem to get a glowing frame on. Is it this that stopping me getting to any more battles or something else?
Sorry if this sounds like a daft question. Have been through all the pages of this help section and no-one else seems to have a similar problem.
H_Bear, Sounds like you have an instance error or you don't have enough hdd space dedicated to the game. I'd refresh first, then if that doesn't work, right click and increase the allowed space for armor games.
