2048 is the sliding-tile game created by Gabriele Cirulli in 2014 (itself based on 1024 and Threes). This version, with its daily challenge, replay-verified leaderboards and native Android app, was made by hackdict on 24 October 2026.
The code, the visual design and the tile palette were written by Claude Opus 5.5 working in Claude Code (Anthropic), directed by hackdict. No generative AI runs while you play: the board, the scoring and the leaderboard are plain deterministic code.
How the leaderboard stays honest
A ranked game starts with a seed issued by the server. Your phone or browser records each move (up, right, down, left) and saves the game every few moves; each time, the server replays every move from that seed and computes the score itself, so a score can only come from a game that was really played. Daily games use one seed for everybody, so everyone gets the same tiles, and you can race the leader's game move for move. Games played impossibly fast are kept off the boards.
Your account and data
2048 uses your Verimots account: signing in on one signs you in on the other. To rank you, 2048 stores your account id, a public name (your first name and the initial of your surname), and for each ranked game its score, biggest tile, number of moves, time taken and the move list. Anyone can watch a ranked game from the leaderboard as a replay, under that public name. Without an account, classic, daily and Blitz games are saved under a random id made by your browser or phone: they are never shown on the boards, and they become your account's if you sign in on that device. Practice games stay on your device. Account deletion follows the Verimots privacy page.
