Ultra Game / Molecular
Molecular
Build complete molecules by connecting atoms with the correct single, double and triple bonds. Each compact board asks you to read valence, balance every connection and find an elegant solution with no loose ends.
Molecular is a connection puzzle in which every atom announces how many bonds it needs. Your task is to turn a scattered field into one complete structure: neighboring atoms can carry single, double or triple bonds, every number must be satisfied, and the final molecule must remain connected.
A move changes the bond between two adjacent nodes. That makes the puzzle easy to touch but demanding to reason about, because satisfying one atom can consume capacity needed elsewhere. Compact opening boards teach the notation before the campaign expands into larger patterns across 20 chapters and 500 distinct levels.
Daily challenges, hints, boosts and visual notebook themes support different styles of play without replacing the core deduction. The best approach is to treat each remaining bond count as a constraint and repeatedly look for atoms whose options have become forced.
How to play
- Read the number on each atom; it is the total bond value that atom must receive.
- Tap or swipe between neighboring atoms to cycle through single, double and triple bonds.
- Balance every displayed count while keeping all atoms in one connected structure.
- Correct contradictions early instead of completing one corner in isolation.
Features
- 500 logic patterns across 20 chapters
- Single, double and triple bonds with clear numerical constraints
- A shared daily puzzle and optional solving aids
- Multiple visual themes that change presentation without changing the rules
First-run tips
- Start with atoms whose required count equals all available neighboring capacity.
- After placing a bond, recalculate both endpoints rather than only the atom you started from.
- If two groups cannot connect later, undo before filling their remaining counts.
