TNT Every 15 Seconds
by mittensDev
Every 15 seconds, a TNT block spawns somewhere in the world on a server running TNT Every 15 Seconds, and players have to deal with it.
What it does
The Minecraft TNT Every 15 Seconds mod is a server-side minigame that places a TNT block every 15 seconds. It is packaged as a Fabric, Forge, NeoForge and Quilt mod, and a Data pack release exists for servers that prefer that route. The mod's own files are published for 1.21 – 26.3, with the latest build 1.4+mod for 26.3 dated 2026-09-29.
Players are meant to survive the timer and build or move quickly to keep the TNT from catching them. Only the server needs to run it, so a server operator installs the mod while players can join without it. The code is open source under the Apache License 2.0, and public links exist for the source code and the issue tracker.
Listing dates: the mod was first published on 2025-12-16 and last updated on 2026-09-29. Snapshot builds are not mentioned in this card.
Key features
Timed TNT spawns
A TNT block appears every 15 seconds, turning the game into a race against a steady countdown.
Challenge play
Players can use the timer to test themselves, for example by trying to beat the Minecraft TNT spawns in a set period.
Server-side setup
Only the server needs the mod, so a group can use it on a server without asking every player to install anything.
Datapack option
A Data pack release is available for servers that do not want to run a loader-based mod.

Hardcore-style challenge
Players who want a harder run can add the timer to an existing world and try to beat it.
Who it’s for: The mod suits server owners who want a simple minigame with a fixed timer and players who enjoy short survival challenges. Players on a server that runs it do not need to install anything.

What the author says
This is a VERY challenging datapack. But why not make it even more difficult by turning on Hardcore? I have seen one of my friends beat this challenge before so it is possible but very very difficult. Try my other datapacks! Here are some that you might like.
