Clear filtersStarting on an island with nothing under you
Skyblock hands you a small floating island, a tree, and a chest with a lava bucket and ice in it. Everything after that comes out of a cobblestone generator and careful trades. The original map was a challenge you finished; on a server the loop is bigger, with island levels, an island leaderboard and a race against everyone else on it.
Server skyblock has drifted a long way from that map. Most now include island upgrades, minions or spawners that farm while you are offline, custom enchants, and a player market where cobblestone is worthless and mob drops are the real currency. That is fun, but it also means progression is tuned around how much you play — or how much you spend.
Before you pick one, check the island team size, whether islands reset each season, and how the shop prices sell-back items. A server where selling wheat pays better than a mob farm is a server whose economy will be flat within a fortnight. Asking in Discord whether the top islands are free-to-play usually gets an honest answer.
1.12.2 is still the default for modded, and here is why
Version 1.12 arrived in 2017 with concrete, glazed terracotta, parrots, the recipe book and advancements replacing the old achievement list. It is remembered for none of that. It is remembered because 1.13 followed it with the flattening, which removed numeric block IDs and rewrote how the game stores world data.
That break stranded an enormous amount of work. Forge mods written for 1.12.2 could not be ported cheaply, so the packs people had spent years assembling stayed where they were, and 1.12.2 became the most played modded version in the game's history. Large packs and their servers are still running on it today.
If you are joining a 1.12 server, expect Forge, expect a launcher profile pinned to 1.12.2, and expect an older feel: no netherite, no raids, no bees, and terrain that stops at Y=0. In exchange you get a mod ecosystem nothing since has quite matched for sheer size. The final patch landed in September 2017 and the version has not moved since, which is exactly why pack authors trust it — a modlist assembled today behaves the same as one assembled five years ago.
