Slime Chunks in Slime Finder and ingame Does Slime Finder work with Bedrock Edition? The only way to find Slime Chunks ingame without using third party apps or mods is to observe the slime spawns. Slime Chunks are predetermined by your savegame seed, and are always the same for a specific seed, just like the generated terrain. Chunks are 16x16 blocks wide (x and z axis) and 256 blocks high (y axis). Apart from spawning in swamps (added in 1.4), slimes can only spawn in every 10th chunk in average ('Slime Chunks').
