Rounds

in Gem Tower Defense, Rounds consist of placing Gems, and then using said gems to defeat a wave of enemies. Each wave is different, increasing in difficulty as the game progresses.

Gems
At the start of each round, you are given the chance to place the gems on the board. Out of the five placed, you may keep one gem. If you get two gems of the same quality and type, you may combine them to create a gem of the same type, and a quality higher(Ex: Two Chipped Rubies become a Flawed Ruby). To do so, select the gem that is in the position you want to keep, and click the "Combine Gems" button.

Alternatively, if you manage to get all the requirements for a Combined Tower, you may combine all 3 gems by clicking the "Special Combine Gems" button on the gem in the position you want to keep, and perform a One-Shot Combo. The game will alert you when a Combo is available, and highlight which gems are combinable.

Waves
Once your Gem for the round is selected, a wave of enemies will appear, walking to 7 different wave points before reaching their goal point. Once an enemy reaches a Goal Point, you lose a Life Point. Once your life points have run out, you lose the game.

The enemies for each round change with various armor types that make them weak to the gem matching their armor type(Taking more damage), and resistant to it's opposite(taking less damage). The exception to this rule is Boss Armor, which takes less damage from all gem types.

When an enemy unit is killed(or a group of enemies in Swarm Mode), you will gain resources to be used for various purposes. Upgrading your Gem Quality chance, your combined towers, or Lucky Chance. if an enemy reaches the Goal Point before you can kill it, those minerals are lost.

The wave and the round end when all the enemy units have been killed, or the last enemy unit reaches the goal point. There are a total of 51 waves, and every 3 rounds starting at Wave 4 will be Flying Enemies. Flying enemies ignore all mazing stones and gems when moving, and cannot be hit or affected by some gems(Like Diamonds or the Aura from Paraiba Tourmaline).

In Damage mode, there is a special boss after wave 30 that will take a life for each Way Point touched. Defeating him gives
