Nonogram Launches — the 15th Game in the SynerWorlds Family

Today the SynerWorlds family welcomes its 15th member: Nonogram is officially live — free, no install, just open your browser and play, with a bilingual Vietnamese–English interface.

What Nonogram is — a Picross logic picture puzzle

Nonogram, also known as Picross, is a logic picture puzzle: you read the number clues at the head of each row and column to deduce which cells to fill and which to leave empty. Fill them all correctly and a picture gradually emerges from your own deductions — no guessing, just logic.

The launch library holds 90 pictures, and every one has been machine-verified to have a unique solution reachable by pure deduction — no puzzle ever forces you to guess.

The rules, as played

• 3 board sizes — 5×5, 10×10 and 15×15 — × 3 difficulty tiers, so you can pick a puzzle that fits your time and experience.
• The 3-mistake rule: a wrong fill is removed and counts as a mistake — 3 mistakes ends the attempt.
• Marking a cell ✕ is never punished — freely note the cells you are sure are empty.
• Logic-based hints — when you are stuck, a hint points to a cell that can be deduced by logic, without filling in the answer for you.
• Win, and the picture is revealed in full color.

What you can play

• Solo play across 90 pictures in 3 sizes × 3 difficulty tiers — from a quick 5×5 introduction to a 15×15 board for seasoned solvers.
• 3 new daily puzzles every day — one new puzzle per board size, every day.
• Race rooms for 2–4 players — everyone solves the same picture, and the fastest correct finish wins, with rankings and ratings.
• History, replays and leaderboards to follow your progress from game to game.
