Thornhold is a forest-defense autobattler where water is your most powerful weapon, and you choose where it flows. Shape the forest and protect the Great Tree from lumber-hungry orcs. Route a river across a grid, place tree structures and troops, and survive waves of escalating orc hordes. Every cell you connect, every terrain you activate, and every card you play … Thornhold is a forest-defense autobattler where water is your most powerful weapon, and you choose where it flows. Shape the forest and protect the Great Tree from lumber-hungry orcs.

Route a river across a grid, place tree structures and troops, and survive waves of escalating orc hordes. Every cell you connect, every terrain you activate, and every card you play shapes the battlefield.

The River Changes Everything. The path you carve determines which bonuses fire, which groves you awaken, and whether your Forest Core gets the power it needs to survive.

Seasons Shift and the Map Transforms. Every few waves, the season changes, and all terrain bonuses rotate. Adapt your strategy to survive.

Draft. Grow. Fight. Draw from a pool of 20+ cards - structures that auto-attack, troops that march into battle, and mutations that stack bonuses. Read more
