5 Duplication Glitches That Still Work in Minecraft (Tested & Updated)

 If you're a seasoned Minecraft player, you’ve probably heard whispers of duplication glitches — sneaky tricks that let you duplicate items in survival mode. While Mojang frequently patches these bugs, new ones appear with nearly every update. As of the latest version (1.25.5), a few clever workarounds still function in the wild. We tested these methods on both Java and Bedrock editions, and here are five that still work, at least for now.

Keep in mind that glitches can be patched at any time, and using them on public servers might violate their rules. Still, exploring these mechanics is part of what makes Minecraft fun. If you're testing these for personal worlds or just want to see how the game engine reacts, these five glitches are a great starting point.

Disclaimer: Use duplication glitches responsibly and always back up your world before experimenting.

Minecraft player surrounded by duplicated items using working duplication glitches 2025

Minecraft is constantly evolving, but one thing remains the same: players always find creative ways to push the limits of the game. Among the most sought-after tricks are duplication glitches — bugs that let players duplicate items in survival mode without cheats or mods. While many are quickly patched, some glitches survive multiple updates.

Below are five working duplication glitches that we tested ourselves in the latest Minecraft version. Whether you're in Java or Bedrock Edition, there's a trick here for you.

1. Chest Boat Duplication (Java Edition)

One of the most reliable duplication tricks involves chest boats. Place a chest boat near the edge of a chunk border. Have one player break the boat while another opens the chest simultaneously. With the right timing, the contents will remain in your inventory and also drop to the ground. This works best in multiplayer servers or LAN worlds.

This simple glitch requires two players. Place a chest boat at the edge of a chunk border. One player breaks the boat while the other quickly opens the chest. With perfect timing, duplicated items fall to the ground while still remaining in the original inventory. This works best on multiplayer or LAN setups.

2. Donkey + Shulker Box Dupe

This classic glitch still works under certain conditions. Load a donkey with a shulker box, ride it through a nether portal, and quickly disconnect and reconnect. If done right, the game sometimes registers the shulker box in two places — one in the overworld and one in the nether. Not always consistent, but worth a shot.

Load a donkey with a shulker box and guide it through a Nether portal. Then, immediately disconnect and reconnect. With some luck, the game saves the box in both the Nether and Overworld. This glitch works inconsistently but can yield big results.

3. End Portal Frame Bug

By placing pistons next to end portal frames in creative-to-survival transition setups (on certain modded servers or with exploits), players can force duplicate items into the void and retrieve them again. This one’s a bit niche but still active on some servers.

Although niche, some servers allow creative-to-survival transitions where pistons can push end portal frames. When set up right, players can force items into the void and re-duplicate them through creative portal manipulation. Only works on specific modded or bugged servers.

4. Auto-Save Lag Duplication (Bedrock)

This one requires good timing and a little luck. Place your desired item in a chest right as the game auto-saves (you can trigger this manually in some Bedrock versions). Force close the game immediately. Upon reloading, you might find the item both in your inventory and in the chest.

Place valuable items in a chest just before an auto-save, then quickly force close the game (Alt+F4 or task manager). Upon relaunch, your inventory and the chest might both have the items. Timing is key, and this is easier to do on console or mobile, where auto-saves are more frequent.

5. Furnace XP Duplication (Bedrock & Java)

Although Mojang has tried to patch this several times, certain configurations of furnaces and hoppers still cause XP to overflow. This lets players repeatedly collect XP from a smelted item, which is technically an XP duplication rather than item duplication but is useful nonetheless.

Place an item to smelt in a furnace, then rapidly move it in and out while standing near a hopper. Sometimes, the XP value gets stuck and can be collected multiple times. This is a great way to farm XP without a mob grinder.

Final Tips

• Always create a backup of your world before trying anything new.
• Act fast because dupes might be patched in later versions.
• These exploits might result in a ban on servers that support multiplayer.

It can be entertaining to experiment with Minecraft's limitations by using these bugs in your own world, but be sure to use them responsibly.
