O’Block is a block puzzle with a deadline. Every day there is one board, the same for everyone on Earth, and one attempt to make it count. Drag pieces onto the 8×8 grid. Fill a row or a column and it clears. Chain clears to grow your combo, then see where your score lands on the worldwide leaderboard. Tomorrow, a new board. THE DAILY One seeded puzzle per calendar day, identical everywhere. One attempt, no retries. Wednesdays add preset stones, Fridays are a 20-piece Sprint, Sundays a 40-piece Marathon. Keep the streak alive. CLASSIC The endless mode, with a twist that changes everything: clear lines through ink cells to charge the ink meter, then swap a piece you don’t want for the one you do. A puzzle where you earn your luck. JOURNEY Twelve issues, one a month. Each issue is twenty crafted levels with target cells and a fixed queue of pieces, and each brings a new twist: edges, walls, heavy pieces, a lattice, a finale. Finish with pieces to spare for three stars. Every level is solvable: by construction, not by hope. Stuck? A hint always shows a move that still wins. NO SIGN-UP, NO NOISE No account. No ads. No tracking. Pick a name, pick an avatar, play. A daily reminder is there if you want it, off until you say so. Your progress lives on your device, and the leaderboard sees only the name you choose. DESIGNED, NOT DECORATED Two colors, one serif, a blueprint grid. Light mode is blue, dark mode is orange. That is the whole palette, and it is enough. O’COINS Earned by clearing lines, claimed once a day in the shop, or bought. Spend them on a continue when the board fills, an undo when one move deserves taking back, or a hint in Journey. Never in The Daily: there, everyone plays by the same rules.
