Solitaire (Easybrain)

This is Klondike, the solitaire most people know: build the four foundations from ace to king by suit, and arrange the seven tableau columns in descending order with alternating colours, drawing from the stock one card or three at a time. Easybrain's version scores each game on time and moves, with multipliers that grow as you move through stages with consecutive wins, and a weekly score shown at the top of the table.

The Daily Challenge is a separate game each day. Win it to earn that day's golden crown; collect the crowns across a month and you get a unique trophy for it. The challenges sit on a calendar of the month, so you can see which days you have won. Seasonal events add sets of deals at several difficulty levels that uncover themed postcards, such as the Halloween event Google Play announces for late October, and timed tournaments rank players on a leaderboard by total or best score.

Undos, hints and a Joker card help when you are stuck or out of moves, cards can be moved by tap or drag, and backgrounds and card backs can be changed. The app is free with ads, including ads between games that players mention in reviews; a one-off purchase removes them. It can be played in English and 18 other languages, and it comes from Easybrain, which also makes Sudoku.com, Killer Sudoku and Number Match.
