For “Element TD” , given below are some tactics and strategies.

1. General Strategies

   Sell any towers that you will not use in next round. Do this before killing last creep. That will help you gain interest on the money. Overlap as many towers as possible till there is one white square and no red squares showing. The maze doesn’t allow placement of balanced tower. Choose top right , center, top left and bottom right for placing towers.  Bottom row and bottom left can be covered by fire towers placed elsewhere.

Combo Towers

If you use lumber to build the elements faster to get rocket towers,  you will not have enough money to get through 29th level. So instead use, first 2 lumbers to increase interest rate & build the cannon towers. Also get sir towers on air levels but sell them afterwards for getting interest on money. Then replace cannon towers with fire towers. Research water towers. Use these both towers to control top corners and maps’ center.

Single Towers

2. Instead of upgrading towers and getting all the elements as fast as possible , get fire towers as early as possible. Then spend rest of lumber to upgrade interest rate. Build only level 1 fire towers and fill out entire map. As you advance to higher level, you can start upgrading the towers.
