About
Nibwell is a calm-but-tense puzzle of containment. A virus blooms across the petri dish — your job is to wall it in with well-placed drops of ink before it takes over.
Every dish is different. Colonies creep, spawn, and — if two ever touch — double their growth. Read the spread, build firebreaks, and claim the dish before the outbreak does.
THREE WAYS TO PLAY
• Classic — a rising ladder of tougher strains, from a single Petri Dish to a full Pandemic.
• Timer — a time-attack race; seal each dish to bank seconds and keep the run going.
• Survival — one clock, one dose supply, an endless stream of escalating dishes.
• Daily Challenge — a new outbreak for everyone, every day.
DESIGNED TO RESPECT YOU
• No ads. No tracking. No data collected.
• One-time Full Game unlock for Hard Mode, plus optional cosmetic ink sets. That's it.
• Unlimited undo, a colour-blind palette with pattern fills, and dyslexia-friendly text.
Contain the outbreak.
