Periodic table games
5 of the 7 games above are built on the periodic table: element symbols, element names, atomic number, and the trends that run across a period and down a group. Acid Boy & Base Girl moves on to acids and bases, pH, and neutralization; Molecule Hunter to molecular geometry and bonding. You answer chemistry to play — the questions are the moves, not a quiz bolted onto a game.
- Bond Forge — Periodic table
- Chemistry-question dots and boxes. Answer right to draw a bond; close boxes to score and go again.
- Pt Paddle — Periodic table, Atomic theory
- Play the Platinum Arena: answer chemistry questions to grow your molecular paddle, then steer it into the ball’s path. Keyboard, mouse, and touch controls.
- Run the Table — Periodic table, Atomic theory
- Beat the clock filling in the periodic table from memory. Blank one and it lights up red so you know what to drill.
- Acid Boy & Base Girl — Acids and bases, pH, Neutralization
- Two heroes. Five rooms. Read the pH scale, test each tile with the right hero, and neutralize a solution to open the way through.
- Molecule Hunter — Molecular geometry, Bonding
- Hidden-fleet deduction. Hide your molecules; hunt the opponent's. Every shot is gated by a chemistry question.
- Capture the Nucleus — Periodic table, Periodic trends
- Hidden-rank tactics. 12 ranks map to periodic-table groups: Spy beats Marshal, Miner defuses Bomb. Every attack is a question.
- Storm the Castle — Periodic table, Bonding
- Turn-based chemistry siege against Cobalt or a friend. Answer to muster an army, commit your line, storm the keep by the unit counter-triangle.
