| Chiikawa tokens | Exactly one per row, per column, and per colour region; two tokens cannot touch, including diagonally. | Official |
| Character roster | Unlockable with coins; cosmetic only — never changes the grid, difficulty, or payouts. Prices and most names unpublished. | Official + community wikis |
| Hearts | Wrong placements consume hearts; recorded runs show zero-heart sequences, and a Heart + 1 pass (149 Robux) exists per the community wiki. | Fan guide + community wiki |
| Win streaks | Named on the official Standard row. Consecutive clears build a streak; restoration and persistence after a loss are undocumented. | Official + community wikis |
| Coins | Earned through Standard play, daily missions, and endless streaks; spent on character unlocks. The game's only named currency. | Official + community wikis |
| 2x Rewards Pass | A 249 Robux game pass per the community wiki's pass table — payout speed, not solving power. | Community wiki |
