Haeux Bond

This app is a lightweight chemistry-themed puzzle game that turns textbook symbols, ions, and states of matter into hands-on challenges.

• In Water Purification, you learn to tell heavy metals and acid–base pollutants that must be removed from minerals that should stay in the water, across twenty progressively harder levels that sharpen your sense of water quality and safe limits.

• In Bond Link, you flip and match tiles on a honeycomb board—from single, double, and triple bonds to π bonds, reaction arrows, and more—finding identical symbols in pairs through twenty levels that grow in difficulty, helping chemical notation stick in memory.

• In Phase Sort, you read a substance’s name and formula and decide whether it is a solid, liquid, or gas at room temperature, answering twenty rounds in a row and building streaks for bonus points, connecting abstract ideas to everyday intuition.

Each mode offers a full long-form run. Whether you finish or step out midway, your session is logged; ions filtered, pairs matched, answers given, and campaign results accumulate over time, and achievements tied to real chemistry practice unlock as you play—ideal for short bursts of play that help knowledge settle in and feel useful, not just memorized.
