Minecraft 1.21+ ยท NeoForge ยท Free & open source

Waterslides that
run uphill.

Lay cheap channels, drop in RF-powered jets, and ride enormous slides โ€” downhill, uphill, through glass tubes you flooded yourself, effectively forever. No grind, nothing rare. Build it. Ride it.

What it does

One craft paves 16 blocks. Build BIG.

๐Ÿ›

Channels snap like rails

Straights, corners, and slopes sort themselves out as you place them. Always full of water, no supports needed, dyeable in 16 colors.

๐Ÿš€

Jets push any water

Each Jet drives a ~24-block current through the water ahead โ€” slide blocks or plain water alike. Redstone switches them off.

โ›ฐ๏ธ

Uphill is a feature

A climb costs exactly what a drop pays, and jets re-pay the climb โ€” so slides can loop, spiral, and go on effectively forever.

๐Ÿซง

Tubes & drop shafts

Enclosed tubes commit you to the ride โ€” window strips to see out, vertical shafts that bank speed for a screaming exit.

๐Ÿ—๏ธ

Glass megastructures

Build a watertight glass tube of any size and the Flood Valve fills it โ€” and if it isn't sealed, it points at the leak.

๐Ÿ›Ÿ

Safe by design

No fall damage while riding. Splash Pools swallow any landing. Crouch to brake, jump to bail โ€” unless you're in a tube.

How it works

Three steps, splash included.

01

Lay the line

Slide Channels auto-connect as you place them โ€” downhill, uphill, around corners. Gravity alone starts the ride.

02

Power the push

Place Jets along the run and feed them RF โ€” the built-in coal- or water-fed Pump House, or any RF mod's generators.

03

Hop in

Crouch to brake, jump to bail, land in a Splash Pool. Mobs and dropped items ride too.

Rules of the water

Fun-first physics, honest limits.

~22 blocks/sec cap

Fast enough to feel reckless, tuned to stay under the server's movement ceiling. Configurable.

Symmetric slopes

Climbs cost what drops give, block for block. Endless loops aren't an exploit โ€” they're the point.

Cheap power

One coal in the Pump House runs jets for a long while. Or skip it โ€” any RF mod's cables plug straight in.

No chunk loading, ever

You load the world as you ride โ€” a park can span a hundred chunks and only the parts near players tick. Mobs and items pause when you leave; that's by design.

Versions

One codebase, a jar per version.

Built with Stonecutter โ€” every supported NeoForge target gets its own jar from the same source tree.

Get it

Grab a jar, build a park.

Releases ship on GitHub โ€” one jar per Minecraft version, pick yours and drop it in mods/. A CurseForge listing is on the way. Optional: install Patchouli and craft a book with any slide channel for the in-game Park Builder's Manual.
