Gem Monsters is a competitive match 3 falling puzzle game with summons.

Match 3 like-colored gems to smash them, and outlast the other player. If the gems reach the top of your screen, you lose.

There are 5 summon monsters

• Red - Pyroclastic Roar - ash rains down on your opponent
• Green - Wind Slash - on your board, smash every gem of a random color
• Blue - Tidal Crash - a tsunami crashes against the cliff face, eroding it
• Yellow: Justice's Light - balance both play areas
• Purple: Grim Gravity - your opponent's gems fall faster

When the bar is empty, the first gems you smash will determine the color of the summon you work towards. When you smash enough gems, the summon bar will fill up completely. Then, you press the SUMMON button to activate the monster and its effect. You can drain the bar at any time with the DRAIN button. Use this to reset the summoning color so you can work toward a different color.

When you or an opponent summons Yellow, odds are that the new gems you get will smash in several places. This refills the bars very quickly.
