GemCraft is a tower defense game which was released in 2008 and praised for its innovation. Its full title is GemCraft Chapter One - The Forgotten. In GemCraft, you are a wizard tasked with defending the world from evil hordes of invading monsters.


GemCraft mixes up the classic TD formula with several new tricks. Your defense consists of magically created gems placed atop towers near the path the monsters follow. Various colors of gem offer different types of special attacks. The primary resource in the game is Mana and you gain Mana from killing monsters. If a monster reaches your Wizard Tower, you lose Mana and if you lose more Mana than you have, then game ends. In other words, Mana also acts as your Lives in the game. You can create gems of any grade directly, though higher grade gems are significantly more mana-intensive. However, the gem you get will be of a random color, so if you want a specific gem type you're better off producing a load of low grade gems and combining the ones you want. Placing a gem in a tower enables it to shoot at monsters. Gems can be dropped on monsters as gem bombs, consuming the gem. You may also place Water Trenches in the path of monsters, slowing them down.

Gem TypesEdit

Each gem type has a different ability.

  • Red gems - Splash damage
  • Yellow gems - Chance of doing triple damage
  • Blue gems - Slow
  • Green gems - Poison damage
  • Orange gems - Steal Mana
  • Purple gems - Reduce armor
  • Lime gems - Chance of chain hit
  • Cyan gems - Chance to shock

You can create gems up to grade 6. To get higher grades, you have to combine gems. Gems of different colors can be combined. Dual gems does more damage than Pure gems, but their special abilities are reduced. Combining gems of all 8 colors creates a Prismatic gem.



Gemcraft gameplay

There are 48 levels, including the secret levels. There are 5 Epic levels throughout the game which act as Boss levels. Each level has different available gem types. On Epic levels, all gem types are available.


Monsters come from the monster base in waves. In each wave, monsters have different hit points, armor and speed. The wave stones on the left side of the screen show you the stats of the monsters that will appear. Boss monsters have higher armor and hit points, but there are fewer of them in a wave.


Completing levels rewards you with XP points which counts towards leveling up your wizard. Repeating a level will not gain cumulative XP as only your highest XP score for each level on each game mode counts towards your wizard level. For each level you get Skill points which you may spend upgrading your wizard's skills.
