Reactor: Particle Match Puzzle

Ice is closing in on Cryton38, and the reactor is all that keeps it going. Particles stream down the tube toward the reaction chamber. Tap the one that matches the particle at the bottom, and keep the power coming. HOW IT PLAYS • A match is a good reaction. A mismatch spills sludge into the reactor. • Good reactions in a row build heat, and heat makes power. The hotter the reactor runs, the more each reaction makes. • Heat frosts the tube and hides the particles on their way down. Remember what's coming. • When the sludge reaches the top, the reactor catches fire. Put it out with credits, or let the shift end. • Unlock rare and exotic particles for even more power. MISSIONS AND THE LAB • Work through missions in classes. Finish most of one class to open the next. • Discover elements by how you play (particles hidden, particles combined, the sludge level), then combine them in the Utility Lab: the Particle Peeper, the Sludge Siphon, Kepler's Coolant, the Containment Field and more. • Every 80 KW you produce earns a credit. Spend credits on extinguishers, utilities and mission skips. MELTDOWN MODE Heat climbs with every good reaction and never cools. Choose how many particles it may hide, from 3 to 6 or no limit, and see how much power you can make before the reactor gives out. Each run uses a fusion cell, and the cells recharge over time.
