Tips and tricks
- Learn the first thirty seconds perfectly. The opening is the same every time, so it should never be where you lose.
- Take a short break after three or four failed runs. Arcade games punish tired eyes more than any other genre.
- Combo systems reward patience: keep the chain alive with safe moves rather than reaching for risky bonuses.
- Aim for consistency before you aim for records. A steady run that avoids mistakes usually scores higher than a flashy one that ends early.
- Because this is a Solitaire game, free up the face-down cards before you move cards to the foundations.
- Because this is a Card game, track which cards have already been played.
