How to get the gem you want? Make multiple gems with one click (press the create gem spell, then hold the Ctrl key and press an inventory slot). This gives you many random gems, hopefully including a few of the type you need. Combine them if you want and place them into your towers. The rest of the gems can be useful to make gem bombs. Combine them until you reach a grade high enough to damage the monsters, and use them when the situation looks grim.
How to reach the glowing frame score? If you are at wizard level 40, you have a very good chance to get the glowing frame score on every levels. For most of the levels, you can do it even on a lower wizard level.
Try to get many amulets, e.g. build 10 towers, throw many gem bombs, create and combine many gems.
Click the topmost wave stone every time you feel you can handle the mass of monsters coming. Ideally press it 10 or more times at the beggining of the level.
Reaching the glowing frame score on many levels can unlock hidden stages.
What to do when you face a level which seems to be unbeatable Redistributing your skill points can help a lot. If you have just reached a new powerful skill, don't hesitate to put many points in it, even if it means you will have less points to spare on your previous skills.
Play former levels again to get a higher score. This increases your grand total and possibly levels you up. To see how many points you have to level up, roll over the info panel at the bottom left on the world map, or go into the statistics screen.
If you have unlocked a hidden level, don't try it until you have the pure gem mastery skill.
See the special tactics below, they can help as well.
Make strong points Place your towers so that each of them covers the longest path possible. place your trenches near your towers, so they will give your towers a better chance to halt the advancing monsters. Placing 4 towers and 10 water trenches in a small area can give the monsters a very hard time getting through.
