SYNKO is a 5x5 word-grid game: fill the board, form real words across and down, and rack up points every time a letter gets reused. Every match starts with an empty 5x5 grid and a hand of tiles. Place a tile, complete a word of two or more letters, across or down, and score. The board fills up fast, and the best plays come from setting up future words, not just grabbing the nearest blank. Special tiles change the math: Wild - becomes any letter you choose Switch - replaces a letter already on the board Remove - erases a tile from the board The game ends the moment the grid is full. Final score is the total of every word formed along the way. DAILY CHALLENGE Everyone gets the same tiles, once a day. Beat Par, a target based on a bot's own attempt, to keep your streak alive, then check the leaderboard to see how you stacked up. 2-PLAYER VERSUS Challenge a friend directly or share a room code with anyone. Real-time turns, live chat, and a rematch button when the trash talk demands a sequel. PRACTICE Fresh tiles, no pressure. Play as many rounds as you want, practice games stay off your stats. Track your progress with Stats and unlock Badges for streaks, comebacks, and milestones. Add friends with a shareable Friend Code, sign in with Google or Apple to keep your progress across devices, or jump in as a guest with zero setup. Turn on notifications for daily reminders and 2-player turn alerts, or leave them off, your call.
