Read every square before starting a line
These events reward individual tasks, completed rows or columns, and the finished grid. Begin by marking the tasks you can complete with normal play. Then compare the extra cost of finishing one useful line with the reward it unlocks. A board containing a purchase task is not automatically a free full-clear target.
Plan a line rather than spending at random
- Check whether each requirement counts spending, power gained, completions or purchases. Similar wording can require different actions.
- Time a planned upgrade to satisfy both the grid and another event only when both rules count it.
- Review all squares on a proposed line before spending its rarest material. One unavailable task can prevent the line reward.
- Use the reward tab matching your current edition. Tabs for different seasons are alternatives, not extra boards you can claim together.
Keep the partial rewards in the plan
Completing useful individual tasks and one line can be a better result than exhausting resources for the full grid. Claim finished rewards before closing and keep any uncompleted purchase or late-progression tasks out of your expected total.
