## What is Ennea Sudoku?

Ennea is competitive sudoku with real clocks and no mercy. The timer never stops: pause hides the board, but the seconds keep running. Errors cost 60 seconds, hints cost 30. Three errors on a competitive board and it's over.

FEATURES
- Six difficulties, from Easy to Inferno (near the 17-clue floor)
- Daily Challenge: the same puzzle for the whole world, streaks that matter
- 1v1 Race: send an invite link, same puzzle, fastest time wins
- 18 hand-tuned themes, from Newspaper to Neon Tokyo
- Stats, best times and Game Center leaderboards
- No account, works offline

Ads are rare, elegantly typeset like classifieds in an old newspaper, and appear only after you finish a game - never during play. Ennea Premium (a single one-time purchase) unlocks every theme and removes ads entirely.
