Kaiju Siege

About this board game

Kaiju Siege is a solo worker-placement game for one player, with each game taking about 20 minutes. Set in Japan during the Edo period, it casts you as a warlord sworn to protect your shogun and defend your castle from attacking Kaiju.

No one is prepared for the sudden emergence of these monsters, so you must command a group of peasants and warriors while relying on help from your allies. Your goal is clear: defeat the Kaiju attacking your castle before the end of 10 rounds.

Kaiju Siege offers changing conditions from game to game through a selection of characters, monsters, and missions. Choose from 8 characters, each with variable powers, and face Kaiju that bring their own distinctive threats to the siege.

• 1-player solo worker placement
• Approximately 20 minutes per game
• 8 characters with variable powers
• 5 Kaiju with unique special attacks
• 8 missions that increase the game’s difficulty
• A 10-round objective to defeat the attacking Kaiju

The available characters, unique Kaiju special attacks, and missions give each game a different setup and challenge. Missions can increase the difficulty, while the character choices provide variable powers for your defense.

Whether you are drawn to historical Japan, monster attacks, or compact solo games, Kaiju Siege presents a focused castle-defense experience built around worker placement and a race to survive the full siege.
