Concentration (Matching Pairs)

Good concentration game. Can play from a grid of 16 cards up to a much larger amount. 64 cards I think. Should satisfy anyone who wants to play at any level.

The App has a nice UI and look to the cards. I wish there were two settings I could change: 1. Add an option to start with the cards all face up for a set time. (In miliseconds, Between 0 and 1; with options to input 3digit values of time like 150ms. 2. Numbers on card faces for other 2 sizes. (1 to 8 for 4x4; 1 to 32 for 8x8) The shapes are hard to distinguish quickly for the 4x4 other than their color. I really like 6x6 number faces. I will rate 5 stars and buy the remove ads if you add these.

Beautiful, simple UI. I think it needs a bit of improvement: Please make a preview of all cards at the beginning. I am using this to help me cognitively, long-covid brain fog.
