The Binding of Isaac features hundreds of collectible items that dramatically change Isaac's appearance and abilities. These items can stack and combine in unexpected ways, creating wildly different builds each run and contributing to the game's massive replay value.

Press the spacebar to place a bomb, which explodes after a short fuse and damages nearby enemies and destructible objects. Bombs can also be used to blow open secret rooms hidden behind cracked walls, so keep an eye out for suspicious wall textures as you explore.

A standard run in The Binding of Isaac takes you through six floors across three chapters, each with increasingly difficult enemies and bosses. Every floor is procedurally generated, so the layout, rooms, and items you encounter will be different every time you play.
