About Trinox: Tic-Tac-Toe
Tic-tac-toe as you know it, plus three new ways to play it. You are the Sun; the machine or a friend beside you is the Moon.
FOUR MODES
Classic: 3x3, 4x4 or 5x5. You win by completing a whole row. There is also a reversed variant where completing a row makes you lose.
Eclipse: each player keeps only three marks. When you place a fourth, your oldest one disappears. It never ends in a draw.
Supreme: nine boards inside one. The cell you play sends your opponent to the matching board.
Drop: marks fall down the column until they land. Connect four in a line to win.
THE MACHINE
Four levels: Easy, Medium, Hard and Master. In classic 3x3 Master never slips: the best you can do is draw. In the other modes it thinks for up to a second, and it can be beaten. Hard is tough, but it still lets a move slip now and then.
60 PUZZLES AND ONE A DAY
Each puzzle is a real position: win in two or three moves, or defend against your opponent's threat. A solver checked every one, and each has a single correct answer. You can ask for a hint, and solving without mistakes or hints earns three stars. There is also a daily puzzle, the same for everyone, with a streak of days to keep.
THE REST
• Two players on one device, or against the machine
• Series of three, five or seven games
• Optional move timer
• Undo, hint and a scoreboard for each mode
• Achievements and statistics
• Day and night themes
• 13 languages: English, Portuguese, Spanish, German, French, Italian, Russian, Polish, Turkish, Indonesian, Japanese, Korean and Traditional Chinese
• Sound effects, music and vibration, each with its own setting
Works offline. No ads, no sign-up and no locked content. The only purchase is a coffee to support the studio, and it changes nothing in the game.
