2048 is a quick number-merge puzzle. Slide the tiles around the board; when two tiles with the same number touch, they merge into one. Keep merging to build a 2048 tile and chase the highest score. On Playground by AGLASEM the board is the same for every student each day, so the leaderboard is a fair contest.
Yes. The daily board is seeded so every player gets the identical sequence of tiles that day, which keeps the leaderboard fair.
No — you can play freely. Logging in (or being already signed in to AGLASEM) saves your score, streak and XP, and puts you on the leaderboard.
Your score is the total value of all the tiles you merge. Your best score each day counts towards the daily and weekly leaderboards.
