    • Color-blind mode

      + and − clues use blue/amber and are always readable by shape + sign; never by color alone.

    • Animations

      Turn them off and every transition is instant; this site honors prefers-reduced-motion the same way.

    • Sound

      Sound effects can be switched off in one tap.

    • Auto-submit

      In Adrenaline, the guess is sent the moment you enter the last digit.

    • Language and account

      English · Turkish. Profile, invites, blocked players, sign-out and full account deletion, all in the app.

    Fair play

    No cheating, only logic

    • 01

      Rules run on the server

      Scoring, timers, coins and points are all processed in Cloud Functions. The client cannot write any data directly.

    • 02

      The number never leaves the server

      The number you are looking for is kept only on the server. Even someone reading the network traffic cannot see it.

    • 03

      Server time

      Countdowns follow the server clock, not the device. A player who does not move loses the turn; missing two turns forfeits the match.

    • 04

      Progress tied to your account

      Streaks, points and badges are stored on your account and survive a phone change. Report or block a disruptive player from the leaderboard or after a match.

    Coins and points

    A small economy with clear rules

    • 50 coins · 1000 points

      Your starting balance. Coins are in-game items and cannot be cashed out.

    • 2-coin entry

      Ranked matches. The winner takes the 4 in the pot; a draw returns 1 coin to each player.

    • +25 coins

      When a friend joins with your invite code.

    • Top-up to 4

      If you drop below 2 coins, you are topped up to 4 once a day, so nobody is locked out.
