Descend into the void. Gather strange equipment, shape your build, and see how far it can carry you. Voidle is a dark idle RPG built around automatic combat and the decisions you make between battles. Choose a Warden, Stalker, Occultist or Revenant, then follow your own path through the Skill Graph. Combine skills, passive bonuses and Mutations as you push toward the next Milestone Boss. Fill the Bestiary. Every creature in the depths is hand-inked and animated, from the smallest blob to the ten Milestone Bosses. Meet a creature to add its plate to your Bestiary, and defeat enough of them to fill in its page. Make your equipment part of the strategy. Enchant useful finds, salvage the rest, experiment with corruption, and brew potions for your descent. Artifacts and Ascension Relics open more ways to build. Prestige to earn Skill Points from new depths, then pursue Ascension for another layer of progression. Explore the Compendium whenever a rule needs explaining. Press and hold any dotted term for a quick explanation, then follow it to the full entry. For a different challenge, start a Weekly League save. Each week brings shared generated classes, skills and a Skill Graph, with its own depth leaderboard. Return after time away to claim Away Rewards based on your build. Adjust your equipment, try another route, and descend again.

Verdict
The clearest difference is in-app purchases: SlimeMerge at none against Voidle's 1. SlimeMerge also leads on update cadence (daily vs every 6 days). Voidle's advantage is ads (none vs shown). On price, device support and iOS requirement there is nothing between them.
