Solitaire Cube by Tether Studios is one of the original real-money solitaire apps, continuously operated on the Skillz platform since 2016. With 95,000+ App Store reviews and a 4.62 rating, it has built a solid user base across nearly a decade of competitive solitaire tournaments. The synchronized Klondike format — identical deck sequences for all tournament participants — ensures fair, skill-based competition. It does not match the player pool size of Papaya Gaming's Solitaire Cash, but the Tether/Skillz infrastructure is reliable and the game has stood the test of time in a crowded category.

Full Review
Our verdict on Solitaire Cube
Solitaire Cube is among the oldest real-money solitaire apps in continuous US operation — launched by Tether Studios, LLC on the Skillz platform in 2016, it predates most of its current competitors by several years. That longevity is meaningful in a category where platform trust and payout reliability are the primary purchase criteria for players.
The Skillz platform handles all financial operations — entry fee escrow, PayPal payout processing, and identity verification. Tether Studios focuses on the game experience itself, which has been refined over nine years of continuous operation. The result is a product that shows its age in some UX elements but delivers a reliably functional tournament solitaire experience.
Our verdict on Solitaire Cube
Solitaire Cube earns a strong recommendation for players who want the reliability of a long-operating Skillz-backed product over a newer entrant. It is not the most polished solitaire cash app in the category — Papaya's Solitaire Cash has a larger player base and the AviaGames Solitaire Clash has better recent user reception — but Tether Studios' nine-year track record of paying out on the Skillz platform is a genuine competitive advantage for risk-averse players.
Gameplay
Solitaire Cube uses Klondike Solitaire — the classic format where players move cards in descending, alternating-color sequences across the tableau and build foundation piles by suit. Cash tournament contestants receive the same deck sequence, so the player who scores highest and moves fastest wins. Points accrue for card moves to foundations, completed tableau sequences, and time bonuses. Matches run 2-4 minutes.
Payouts and contests
Payouts are processed via Skillz using PayPal. Entry fees start at $1 for head-to-head matches. Skillz identity verification is required before first cash withdrawal. Processing times are typically 3-5 business days for first payouts; faster for returning verified players.
Availability
Solitaire Cube cash tournaments are unavailable in states on the standard Skillz restriction list (Arizona, Arkansas, Connecticut, Delaware, Louisiana, Montana, South Carolina, South Dakota, Tennessee, Vermont and others). Available in the majority of US states. iOS on the App Store; Android via Google Play.
Final take
Solitaire Cube is a proven solitaire cash platform with a nine-year payout track record on the Skillz infrastructure. For players who prioritize longevity over the most polished interface, Tether Studios' app remains a solid choice in the competitive solitaire cash category.
