ATM - Slabs 'n Stairs
Building in Minecraft is all about variety, and few things limit creativity faster than a block that only exists in its full form. ATM - Slabs 'n Stairs solves that problem by turning dozens of familiar materials into stairs, slabs, buttons, and pressure plates. If you have ever wanted a polished granite stairway or an ice slab path, this mod was made for you.
What ATM - Slabs 'n Stairs Adds to Minecraft
The core idea is simple: take blocks that never had shape variants and give them the full set. You get stairs, slabs, buttons, and pressure plates for mossy and regular cobblestone, smooth stone, red sand, regular sand, and endstone. Polished andesite, diorite, and granite also receive the treatment, which is a huge win for anyone building with those stone types.
The mod does not stop at stone. Ice, blue ice, and packed ice all gain slab and stair versions, plus a mysterious extra ice variant that hints at a deeply frozen biome or dimension. Cracked deepslate, deepslate bricks, and deepslate tiles round out the stone options for the newer versions of the game.
Beyond the Basics: Croptopia and Citrine
There is more here than shape variants. ATM - Slabs 'n Stairs includes support for Croptopia cinnamon wood, adding planks, stairs, slabs, pressure plates, buttons, fences, and fence gates. New soil variants such as Quarter Dirt and Dirt Cobble accept bonemeal, letting flowers and trees grow on them.
A brand-new mineral called Citrine also joins the game, complete with raw gems, blocks, ore, deepslate ore, and even a Citrine Coin for special trading. A Citrine Sword, a Growth Stop Block, light-brown dye, and a Lightning Striker enchantment book for the crossbow are in progress.

Supported Minecraft Versions and Forge Compatibility
This add-on targets Java Edition and runs on Forge. The versioning scheme is worth understanding before you grab a file. The second digit of each version number maps directly to a Minecraft release: 01 for 1.8.x, 02 for 1.12.x, 03 for 1.15.x, 04 for 1.16.x, 05 for 1.18.x, 06 for 1.19 to 1.19.2, 07 for 1.19.3 and 1.19.4, and 08 for 1.20.x. The remaining digits cover major, minor, bugfix, and build numbers.
Tested combinations include Minecraft 1.19.3 with Forge 44.1.8, Minecraft 1.19 to 1.19.2 with Forge 41.1.0 through 43.0.3, and Minecraft 1.18.x with Forge 38.0.17 up to 40.1.80. Older branches for 1.16.x and 1.15.x are also listed. Work on Minecraft 1.20.x with Forge 47.0.35 is ongoing, so check the changelog of the latest build before assuming your setup is covered.
A Note on OptiFine
If you play Minecraft 1.18.2 with OptiFine, the author recommends Forge 40.1.57 paired with OptiFine HD U H7. That combination reportedly runs smoothly alongside roughly sixty other mods, including Biomes O' Plenty and Pam's HarvestCraft 2.
How to Install ATM - Slabs 'n Stairs
Getting the mod running is straightforward for anyone who has installed a Forge mod before.
- Install the correct Forge version for your Minecraft release.
- Download ATM - Slabs 'n Stairs for Minecraft from the official project page.
- Drop the jar file into your mods folder.
- Back up your save game before launching, since the mod is still in beta.
- Start the game and confirm the new blocks appear in the creative inventory.
Because the project is in beta, bugs and issues can appear. The author explicitly asks players to copy their save files before use. Questions, ideas, and bug reports are welcome through the comment section or the GitHub issue tracker. Modpack creators can include it freely, and the source is published under GNU 3.0, so modifications are allowed under the same terms.
If you would rather skip manual file management, the foxygame.net launcher handles ATM - Slabs 'n Stairs through its built-in add-on catalog, so the right build for your game version is selected automatically. That same launcher also pushes auto-updates whenever the author publishes a new bugfix build, which matters a lot for a mod still in beta.
Final Thoughts
ATM - Slabs 'n Stairs fills a gap that vanilla Minecraft has left open for years. Stone, ice, deepslate, and even cinnamon wood finally get the shape variants builders have been asking for, and the Citrine content adds a fresh reason to explore. Just remember the beta warning, keep a save backup handy, and match your Forge version to your game release. With those precautions in place, this add-on earns a permanent spot in any builder's mod list.
