HOW TO PLAY

WHAT IT IS

Daily Challenge is an arcade with a single challenge a day. Every day at 00:00 (Mexico City time) a new game comes out with the same map and seed for everyone: the same snake, the same ghosts, the same pieces falling in the same order.

You play once. Your score goes on the day's board and at 23:59 the Top 10 is frozen forever. No levels to unlock, no purchases: just you, today's map and the scoreboard.

THE RULES

· One coin per person per day. Die after five seconds and that is your score for today.

· Map and seed are the same for everyone, so the board compares skill, not luck.

· Scores are computed on the server by replaying your run key by key. They cannot be faked.

· Ties go to whoever reached the score first.

· The champion of the day gets an extra coin for the next day. If they use it, their best try counts.

SCHEDULE (MEXICO CITY TIME)

· 00:00 — the day's challenge opens.

· 09:00 — we post on Facebook and Instagram which game is on today.

· 15:00 — live board on social media; if someone dethroned the leader, we tell.

· 23:59 — the board closes. Minutes later the podium goes out with names and points.

CHAMPION OF THE DAY

First place at each close is the champion until the next midnight: a crown next to their name everywhere, an extra coin for tomorrow, and they can leave a message that shows on the game's home screen, on that day's page and in the morning post. Sixty letters to say whatever they like (swear words come out as asterisks).

Writing the message requires signing in with Google, so the name and the crown belong to a real person.

All are original versions written from scratch, with Atari 2600 style graphics and sound: 160x192 pixels, a 128-color palette, public-domain music turned into chiptune.

CONTROLS

· Phone: on-screen arrows and button, or swipe in the direction you want.

· Computer: arrows or WASD to move; space, Z or Enter for action.

· It can be installed as an app from the menu (or in Safari: Share → Add to Home Screen) and works offline for practice; the board needs internet.

WATCH THE LEADER'S RUN

Once you have spent your coin, the menu shows WATCH THE LEADER'S RUN: first place's game replays on your screen, key by key, exactly as they played it. It is not a video — it is the run re-simulated, the same thing the server does to verify scores.

It is only available after you play. Not before, and for a reason: with that key log someone could submit their run as their own, and the board would stop meaning anything.

PARTY MODE

Create a room, send the code to your friends and play the same rounds at the same time. Everyone plays on their own phone; the ghost cam shows how the others are doing (and dying). At the end, the sum of the rounds decides.

YOUR ACCOUNT

You can play as a guest with a generated name (NEON COBRA, TURBO ZORRO...). Sign in with Google and that name is yours on all your devices; you can change it and pick your character's color. We never post on your behalf; the only public things are your player name and your score.
