Timing and resolution order

Reactomino has three ways of advancing time. Knowing which one an effect uses helps you decide whether waiting is safe.

Three kinds of time

Time	What advances it	Main effects
Map exploration	Completing nodes	Day count, time of day, daily modifiers, and map weather
Battle turns	Successfully placing a piece	Enemy actions, turn-based restrictions, periodic weather, and bottom pressure
Ongoing board activity	Time passing while battle is running	Sand, fire, liquids, mechanisms, TNT, and moving objects

Selecting, moving, or rotating a piece is not a placement. Casting an active skill does not add a placement turn either. However, material reactions can continue while you aim. Pause when you need time to read.

The broad order of a placement

Check the landing position → place blocks and liquids → determine line clears → deal placement damage → record SPIN / COMBO and resolve clear rewards → resolve contact reactions → advance turn statuses and the queue → advance enemies, bottom pressure, and weather.

This is why a single piece can produce both placement and line-clear damage, and why an enemy may act immediately after you place it.

Chains after placement

Falling sand, mechanisms, explosions, and liquids can change the board and cause further clears. These can advance COMBO and use the natural-chain multiplier.

Clearing several lines at once advances COMBO once. A later, separate clear advances it again. A successful placement that clears no lines breaks the previous COMBO.
