Topic Idle Clans Tools live SimpleMMO Tools live
How you level One ceiling for all 21 skills: level 120, or 500,000,000 XP each, which puts the maximum total level at 2,520.1 One character level: clearing level n costs 50 × n XP, so level 345 needs 17,250. Levels run into the millions — v12.87 added level-up announcements at 25,000 and 1,000,000+. Most of it comes from a travel button: each press is one step and can pay gold or XP from 1 up to your level, an item or a fight.456
Skills and caps 21 skills on a public profile — 6 combat, 15 gathering or production. This site runs 14 calculators, one per skill the game's task data covers, across 263 task rows.21 Four gathering skills — woodcutting, mining, fishing and treasure hunting — each with its own level and tool, plus crafting, which turns the materials into items. Professions replaced jobs in v12.51 and give a stat bonus that grows with rank; v12.86 raised profession XP by 15%.785
Combat 6 of the 21 skills are combat: Attack, Strength, Defence, Archery, Magic and Health. Profiles carry per-boss kill counts — 15 distinct bosses across the 400 profiles we cache.2 Turn-based and decided by three stats: max hit is Strength minus 9/11 of the target's Defence (floor 20), and hit chance is 3.5 × Dexterity ÷ Defence. A special attack costs 1 energy for +25% Strength that turn. Every Monday 12 world bosses and 1 god boss spawn; helping kill one pays 8, 12 or 16 times your level in XP.910
Economy and market A live order book. The public market publishes the highest buy offer, the lowest sell offer and the volume behind each for 630 items, so the spread is readable before you list anything.2 A player market that takes a 3.5% fee once an item sells, plus 2.5% if you buy with gold straight from the bank. Keys and Diamond Shards cannot be listed. The About page claims over 8,000 pieces of loot.1112
Clans and guilds Clans with a shared XP total per skill, recruiting flags and a minimum total level to join. No clan in the tracked top 100 holds more than 20 members.2 Guilds with their own level, capped at 100 and earned through raids, tasks and wars; a guild can opt out of wars by going PvE-only. Founding one costs 15,000,000 gold or 50 diamonds. The About page counts over 1,000 guilds.1312
Where you play Steam, iOS and Android. The official site lists no browser version.3 Browser at web.simple-mmo.com, plus iOS and Android apps, from Galahad Creative, the studio behind IdleMMO. The home page claims over 1,000,000 players; the About page says over 400,000.141215

The read

Idle Clans runs 21 skills to one shared wall: level 120 or 500,000,000 XP each, 2,520 total level when you are done. SimpleMMO has one character level, where clearing level n costs 50 × n XP, and its update notes added level-up announcements at 1,000,000+. Its skill side is narrower: four gathering skills (woodcutting, mining, fishing, treasure hunting) and crafting, each levelled on its own.

Idle Clans publishes the market itself: highest buy, lowest sell and the volume behind each for 630 items, so you can read a spread before you list. For SimpleMMO what is documented is the cost of trading — a 3.5% fee once an item sells, 2.5% extra if you buy with bank gold — and there is no public order book we can point at.

Combat and groups split the same way. Idle Clans spends 6 of its 21 skills on combat and records boss kills on public profiles. SimpleMMO keeps combat to three stats, Strength, Defence and Dexterity, with a documented formula, and 12 world bosses plus 1 god boss every Monday. Idle Clans clans stay small (none in the tracked top 100 holds more than 20 members); SimpleMMO guilds level to 100 and can fight guild wars or opt out as PvE-only.

Devices settle it for some players. Idle Clans is Steam, iOS and Android with no browser version. SimpleMMO runs in a browser as well as on iOS and Android, so it works on a machine where you cannot install anything.
