About Evertrail Idle
Evertrail Idle is a free multiplayer idle RPG that runs in the browser on desktop and phone, in open alpha. You choose a task in one of 18 skills, each going to level 120, and your adventurer keeps at it on their own; progress continues while the game is closed for up to 24 hours. The skills feed each other (ore to the forge, logs to bows and arrows, fish to the hearth, herbs to potions), and Woodcutting and Mining open a new world every ten levels. Everyone online plays in the same worlds and the same town, so other players work the same tree or shore next to you with their names and levels shown. Every two hours a world event starts that anyone can join, such as the Great Oak that everyone chops down together or the Ember Matron, a fire boss; working an event brings in twice the usual haul. There are clans, a player market, global chat, leaderboards, a first dungeon, bosses in five lairs, and an Ironman mode for new characters that plays fully solo, with its own leaderboards. You can start as a guest without an account. The developer, Slapbox98, says most of the code is written with Claude and a fair amount of the 3D art was made with AI tools, with bought base character models, while the developer designs every system, decides every number and tests everything.
How it was built
Partially verifiedIn the AI disclosure of a post on r/aigamedev (27 Oct 2026, UTC) the developer writes: “I use AI tools a lot. Most of the code is written with Claude, and a fair amount of the 3D art was made with AI tools too. The base character models are bought assets.” The developer adds that it is not a “prompt it and ship it project”: “I design every system, decide every number, test everything, and throw out a lot of it when it doesn't feel right.” Which Claude app or model was used is not stated.
Developed over about two months before the post (the developer gives about 1,950 commits since early September 2026), with fixes put out most days, many from bug reports on Discord. Claude wrote most of the code; a fair amount of the 3D art was made with AI tools, and the base character models are bought assets. The game runs on a shared game server, which the 1 Nov 2026 patch notes say was rebuilt to make room for more players; sound and music were added on 4 Nov 2026 as an experimental feature. The engine and languages are not stated.

- Patch notes (official site)
Verification notes: AI use from the developer's post on r/aigamedev by u/Slapbox98 (27 Oct 2026, 12:21 UTC), read from the Arctic Shift Reddit archive on 8 Nov 2026; it had no comments. The post says most of the code is written with Claude and gives no share, so none is recorded. Features, world events, skills, Ironman mode and the patch-note dates come from the official site (home, patch notes, roadmap and community pages), re-read on 8 Nov 2026; the site says its trailer and screenshots come from a test server where the other players are bots. The patch notes start on 18 Sep 2026 and the open-alpha start date is not stated, so no release date is recorded. The 26 Oct 2026 patch notes say a Ko-fi goal was reached and a Steam page has been requested; no Steam page was found, so none is listed. The developer writes in the first person and is identified only by the Reddit name Slapbox98; name, team size and location are not stated. The site's live player counter was not recorded. The game client was not checked for AI service calls; nothing in the sources describes AI used during play. The game was not played.
