"That Summer Week" is a solo, diceless campaign expansion where you follow a seven-day journal instead of rolling dice. Each day provides pre-set number groups (Forecast Groups) you must use strategically to grow your plant, turning the game into a careful planning puzzle.
The expansion mixes growth days with special rest days for interim scoring, adding a new rhythm. A challenging +3 energy bonus for rare six-number sequences tests your long-term strategy, creating a focused and meditative solo challenge.
