First session

The loop is simple once the order is clear.

Roll, combine, place, survive. Save the complicated decisions until the game gives you enough information to make them well.

Roll

Use the roll system to get a starting plant and note what the current menu offers.

Merge

Combine matching plants only after checking which one is already placed or saved.

Deploy

Put your strongest available option on the field before the next wave arrives.

Upgrade

Spend after you see the pressure point. Early upgrades are easier to judge than blind purchases.
