Potion Siege

Play Potion Siege unblocked

Potion Siege is a tower defense game you can play unblocked right here on Physics Shark. It runs in your browser with no download, no install and no account, so you can play it on a school Chromebook, a laptop, a phone or a tablet.

What is Potion Siege?

Brew, merge and defend: living potion bottles hold the castle wall against a clockwork army. Summon potions onto the wall, merge two of a kind into a stronger one, and pick a skill card at every upgrade to build your defence. Fire, ice, lightning and more each fight their own way, and every chapter ends with a clockwork boss. Clear the story stages for stars, unlock hard modes, or see how long you last in endless mode.

How to play Potion Siege

Stop the clockwork army before it breaks the castle wall; survive every wave to win the stage. Click Summon to brew a potion. Drag a potion onto a matching one to merge them into a stronger one. Click Upgrade, then pick one of three skill cards. When the alchemist is fully charged, click him to cast. Mouse only, no keys needed; on a phone or tablet, tap instead of clicking. On a phone, hold it upright (portrait); turned sideways, the game asks you to turn it back. On a desktop or any wide screen, the battlefield lies on its side and fills the screen (landscape).
