ポイ活ソリティア is a free iPhone game developed by MASK LLC. It is a cashback solitaire game that allows players to earn money and Amazon gift cards. By simply playing the classic card game Solitaire (Klondike), users can accumulate points that can be exchanged for cash or Amazon gift cards, making it an ideal app for earning pocket money during spare time.

In ソリティア(クロンダイク), players are tasked with finding cards of alternating colors (red and black) that follow a specific sequence. They must move smaller-numbered cards onto columns with larger-numbered cards. The objective is to turn all the cards face up to clear the game.

The game features simple tap controls, allowing for smooth gameplay even with just one hand. Players can customize the app's background and BGM to their liking. Additionally, hints are available to help players identify the cards they can move, and the undo feature allows them to revert any incorrect moves.

ポイ活ソリティア is recommended for those who enjoy cashback activities, are looking for a side hustle, want to earn extra pocket money, enjoy sweepstakes, are drawn to "free" or "deals," and have a fondness for Solitaire (Klondike). It is also suitable for individuals seeking a casual and long-lasting game app that can be enjoyed alone.
