Guide

Register or play as guest. A guest account works everywhere but can't be recovered if you uninstall — you can convert to a full account at any time from Profile.

Quiz language. Chosen at signup, changeable in Profile. This is the language of the questions, separate from the app's UI language.

Nationality. Optional. Sets the flag next to your name on leaderboards and lets others filter rankings by country. Can be changed once every 30 days.

First practice. The Practice mode is a good sandbox: bots at your chosen difficulty, no effect on your rating. Get used to the read-then-answer timing before your QELO's on the line.

Home. Featured contests, quick-play buttons, "Top Players Today", your daily challenge status.

Lobby. The full list of live and upcoming contests, filtered by type and topic.

My Contests. Your entries — Live (currently playing), Upcoming (joined but not yet started), and Completed history with results.

Rankings. Leaderboards — QELO, Knowledge, or XP — filtered by period (daily / weekly / monthly / alltime), country, tier, and league.

Profile. Your identity: QELO card(s), stats (Games, wAcc, Speed), Knowledge Map, achievements, badges, friends, settings, shop, wallet history.

Practice. Solo vs bots. Doesn't affect QELO. Use it to warm up, learn a new topic, or drill question types before ranked play.

Anytime (Scheduled). Ranked contest with a deadline (usually 24 hours). You play alone against the clock and get ranked against everyone else's scores when the deadline hits. Includes staples like Daily Rookie / Daily Pro / Daily Genius.

Realtime. All players see the same question at the same time on a live server-driven timer. Fastest correct answer wins the round. Answered together, ranked together.

Head-to-Head. 1v1 realtime match. Matchmaking pairs you with a similarly-rated opponent, or you can challenge a friend directly. QELO moves after each match.

Series. A container for multi-round contests. Three variants: Best-of aggregates scores over several rounds; Knockout eliminates the bottom % after each round; Survival gives you lives and eliminates you at 0.

Each question has a short "reading" window (the question is on screen but the timer hasn't started), then an answer window (~10 seconds by default). The scoring curve has three zones:

• Instant zone — first fraction of a second. Correct: max points (~11.5k on a 10s window). Wrong: −2k penalty (this is the "don't reflexively pick" deterrent).
• Bonus reaction zone — the last moments of the reading window. Correct: near-max, sliding down. Wrong: reduced penalty.
• Main timer — the countdown you see. Correct: linear decay from ~10.7k down to ~1.5k. Wrong: full penalty for the first ~4/7 of the window, fading to zero by the end.

No answer = 0 points. Timing out is safer than guessing wrong, but skipping gives no score either. The design rewards knowing the answer + answering quickly, without punishing you for taking your time when you're unsure.

QELO is a Glicko-style rating adapted for trivia. Two players play the same question set: whoever scores higher "wins" that head-to-head, and the ratings adjust based on how surprising the outcome was. Beating someone rated well above you moves your rating a lot; beating someone rated well below you barely moves it.

Placement matches. Your first 5 rated games form a "provisional" period — your rating changes are amplified so you settle into the right tier fast, rather than grinding 50 games to escape 1500.

Per league. QELO is scoped to each league you play in. Your main-league QELO is your canonical rating (largest pool, most stable). Custom-league QELO is separate — the opponent mix is different. Your Profile shows both when you're viewing a custom league.

Practice, unrated modes, and contests where you're the only player don't move QELO.

Tiers are QELO ranges. Each tier is a solid chunk of rating points — Bronze roughly covers the entry range, Silver above that, and so on, with Master at the top. Exact boundaries are hidden intentionally so you play for the number rather than the label.

You move between tiers by playing ranked matches. Consistent wins over ~10-20 games in the tier below is typically what it takes to climb, matching the Glicko rating math.

The Profile tier reflects your main-league (global) QELO. In a custom league you see a separate per-league tier too — a small friend league might have you at Diamond while your global rating reads Silver, or vice versa.

A raw accuracy of "8 out of 10" doesn't say whether the 8 you got right were easy or hard. Weighted accuracy (wAcc) fixes that: harder questions count more toward your score, and there's a guessing-adjustment so you can't inflate accuracy by clicking randomly on easy questions.

The formula is (4·correct_w − total_w) / (3·total_w) × 100, where the _w values are weighted sums per topic. That gives you a score from -33% (random guessing) to 100% (perfect on the hardest questions).

Why Knowledge is global. The question pool is the same for every league — your knowledge of History or Sports is a property of you, not of which league you happened to play in. So we aggregate across all your games, everywhere.

Global league is one giant pool of all Qazaro players. Public daily contests (Daily Rookie, Daily Pro, etc.) all live here. Your global QELO is your "canonical" rating.

Custom leagues are self-contained. Members join with an invite code (or via a /join/XXX link). Admins can schedule contests, run tournaments, pick question topics. Each custom league has its own QELO leaderboard — separate from your global rating.

Sharing an invite. League admin sends the code or the short link. Tapping the link on a phone with Qazaro installed opens the app directly to the Join screen; without the app installed, it lands on the web page with a "Download" fallback.

The XP required per level scales in four tiers:

• Levels 1-5: 500 XP each (0 → 2,500 total)
• Levels 6-10: 1,000 XP each (2,500 → 7,500)
• Levels 11-20: 2,000 XP each (7,500 → 27,500)
• Levels 21+: 4,000 XP each (grows linearly forever)

Coin reward per level-up: 10 (levels 1-5), 20 (6-10), 30 (11-20), 50 (21+ forever). Multi-level jumps in one contest (from double-XP bonuses) sum the coin rewards.

What earns XP. Real-money-adjacent things do not — you can't buy XP. It's a play-time signal, not a wallet outcome. Bot practice earns less than ranked play; harder difficulty pays more; streak milestones give bonus XP.

Ways to earn coins:

• Level up (10–50 coins each, forever)
• Daily chest (once every 24 hours)
• Rewarded ads in the Earn tab
• Streak milestones (bonus at 7, 30, 100 days, etc.)
• Signup bonus (one-time)

What to spend on:

• Avatars — static (300–1,500 coins) or animated variants (600–2,500)
• Frames — decorative borders around your avatar
• Emote packs — for realtime matches
• Chest upgrades — increase daily chest reward

Animated avatar upgrade path. If you already own the static version of a character, upgrading to the animated variant costs only the difference (e.g. static 300 + animated 600 → upgrade costs 300). Buying the animated fresh grants you the static one free.

Achievements unlock once and never lock again. They're global (same across all leagues) and cover play volume (X games played, X questions answered), skill (perfect rounds, win streaks), and social (first friend, first league joined).

Badges are awarded at the end of a period (each Sunday for weekly, last day of month for monthly, last day of year for yearly) to the top players in that window. A Gold weekly badge means you finished top 3 in some league that week. History is preserved on your Profile.

Streak increases by 1 each calendar day you finish at least one contest. Miss a day and it resets to 0. Streak milestones grant bonus XP + coins. The current streak length is shown on Home and Profile.

After finishing a contest, tap "Challenge a friend" to send your score as a target. Your friend gets a notification, plays the same contest at their own pace, and the result resolves automatically. Both parties can add a coin wager up front (winner takes both).

Challenges expire if the friend doesn't accept within a window (varies by contest length). If they accept but don't play in time, they forfeit and you keep both wagers.

• Earn tab — rewarded ads throughout the day, each giving a small coin batch.
• Double XP — offered on the Results screen after some contests.
• Chest upgrades — watch an ad to boost the daily chest reward.

Ads are served by Google AdMob. On EEA/UK/Swiss/California devices, you'll see a consent form on first launch. Ad privacy choices are also accessible from Profile → Settings.

• The flag shown next to your username on leaderboards
• Country filter on the Rankings tab (rank against players from your country)
• Country-specific questions when they exist for your country
• Country contests (occasional themed events)

Why the 30-day limit. To keep country leaderboards meaningful — otherwise players would rotate country to farm easier leaderboards.
