Mentium · Features
Four pillars: an AI that remembers how you play (and now speaks to you), an F2P-viable economy that respects your time, real cultural anchoring across 10 languages, and a social layer with Clubs, wars and async matches.
Mentium runs three layers of personalized AI. They work quietly, without intrusive popups, and you feel them after a few games.
Pick one of 5 personalities (Taunter, Sage, Underdog, Friendly, Calculator). Their memory updates after every match — Classic, AI Category, AI Battle, Debate, Nexus, Detective, Traveler, Daily — and shows up in pre-game lines and post-game reactions.
Taunter 
Sage 
Underdog 
Friendly 
Calculator One motivational message per day, generated by Gemini, with adaptive tone: it picks up on days off, current streak, ignored streak, weak subtopics and recent topics. Ends with an optional CTA (Smart Review, Daily Challenge, Lightning, Nexus, a specific category) — or no CTA when the moment doesn't call for one.
Free adaptive review: 10 questions focused on the subtopics you miss most, kept in an internal buffer. Each correct answer drops the counter until the "You no longer fail at X" banner appears. Only surfaces with ≥3 weak subtopics — never as noise.
Your rival, the Detective's suspects and the Traveler's local guides speak to you in real time with AI voices (Gemini TTS). Each rival personality has a fixed voice — Charon, Puck, Iapetus, Orus or Fenrir — natively multilingual, with local accents in Traveler (a Tahitian guide sounds Tahitian, a Japanese one sounds Japanese). Opt-in from Settings.
Three resources, distinct roles. Purchases exist, but "Remove Ads" is reachable in 25–40 days of play, and the only non-consumable IAP (Rival Pack, €1.99) is purely cosmetic.
Soft, infinite. Earned by playing, spent on premium modes and lifelines.
Premium. Earned via achievements, missions, chests, rewarded ads (1/day) or IAP. Never required.
Cap 0–10. Regen 30 min/life up to 5. Above 5: ads, IAP, chests or won matches.
XP follows an exponential curve; daily streak multiplies XP from ×1.0 to ×2.0.
More than 75 achievements (Bronze/Silver/Gold/Platinum/Secret) totalling 1,360 coins + 713 Mentis, plus 10 exclusive secret avatars.
5 chest tiers with difficulty-scaled drop tables; daily chest auto-roll with published probabilities.
Senda Mentium (new in 2.0): a rewards pass with 100+ levels. Free track with cosmetics, coins, Mentis and chests at every level; optional premium track (€4.99 one-time) with exclusive cosmetics. Non-consumable purchase, levels earned are yours forever.
Each locale has a calibrated LOCALE_FOCUS. Daily generation at 03:00 UTC produces a set of 10 questions anchored to the player's country (or region).

Mentium 2.0 "Einstein" adds the two social layers we were missing: clubs with their own identity and live chat, and a turn-based match system for when you don't want to play in real time.
Create or join a club (public or private), pick a banner and emblem, and chat live with your members. Clubs declare wars against each other, accumulate weekly XP together and compete across league divisions. Includes an invitation system with leader approval, kicks and join requests for closed clubs.
Turn-based async matches: you create the match, pick opponents (friends or club members) and each player answers when they can. Push notification when it's your turn. Supports 2v2 teams, full-match replays and a leaderboard. Built for long rivalries that don't require playing at the same time.
The original social system (search by nickname or tag #XXXXXXXX, daily gifts, direct online duels and an activity feed) stays intact. Clubs and Plaza sit on top of that foundation, they don't replace it.
11 modes, a quick fact sheet for each.
Official wiki with economy, chests, achievements, social and FAQ — all on one page.
