Photon Poker - Earn LTC is a free poker solitaire game developed by Vweeter Limited for Android devices. The game is a unique twist on the traditional game of solitaire, where you place 25 cards on a 5x5 grid and try to score the maximum score for all 10 hands.

Once a card is placed, it cannot be moved or changed, and each column and row is scored as a poker hand. The game allows you to play against AI to test your skills and see if you can score higher than it. By tapping on the AI icon or Player icon in the game screen, you can switch views and play against the computer or other players.

One outstanding feature of Photon Poker - Earn LTC is the ability to earn Litecoin (Photons) while playing the game. To do this, you need to tap on the wallet and register/enter your Coinbase account. Then, play the game and earn at least 100 litoshis (nano Litecoin) to claim Litecoin every 3 days.

Overall, Photon Poker - Earn LTC is a fun and engaging game that offers a unique twist on the traditional game of solitaire. The ability to earn Litecoin while playing the game adds an extra layer of excitement to the experience.
