About this game

The enemy is approaching, but your next defender is buried in the barracks. Sort the troop icons, bring three of the same kind together, and send a soldier into battle before the enemy reaches your castle.

Stackhold combines a sorting puzzle with castle defense. Each move changes which icons you can reach next. A quick match can bring out the soldier you need, but a crowded barrack may leave another unit out of reach.

Sort the barracks
Tap a barrack, then move its top icon to an empty barrack or one with the same icon on top. Each barrack holds three icons. Fill one with three identical icons to deploy a soldier automatically. New supplies arrive in empty barracks while the stacks you have already built stay in place.

Send the right defender
Knights face Goblins on the bridge. Archers shoot flying Bats from the castle. Mages confront Golems on the ground. Watch which enemies are approaching and work toward the match that will help your defense.

Make room as the battle grows
Start with five active barracks. The sixth opens at wave 4, giving you another place to sort your troops. Later waves bring more enemies, and Golems become harder to defeat. If the board leaves you stuck, use Shuffle to rearrange the icons.

The battle continues while you sort. Watch the castle's health, keep room for your next move, and see how many waves you can withstand.
Sort troop icons, match 3, and defend your castle against enemy waves.
