Sometimes, hostile mob spawning may be jammed by mobs that don't despawn automatically.You can safely use Jack-O-Lanterns or Redstone Lamps + Redstone Blocks. But don't use torches on the ground or glowstone, as these blocks will reduce the spawn rate. Use lighting to prevent other mobs from spawning (light has no effect on slime spawning in slime chunks).Waiting in naturally generated caves and hallways will take much longer. It's a good idea to hollow out a 16x16 wide (= 1 chunk) and at least 3 blocks high room inside a slime chunk to maximize the spawn rate.Mobs can't spawn closer than 24m to you (but despawn when farther away than 128m), so don't stand too close to where you expect them to spawn.


Yes! Make sure to select Bedrock as the version. 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").
