Sure! Here's a basic implementation of the alphabet game using JavaScript in a single HTML file. It can be played on a smartphone and uses pictograms for each alphabet.
Alphabet Game
In this game, each time you click the "Start" button, a new pictogram representing an alphabet will be displayed. The player needs to guess the corresponding alphabet based on the pictogram shown. Once the player clicks "Next", the next pictogram will be displayed until all the alphabets are covered. Upon completion, an alert will notify the player that the game has ended.
Feel free to modify and enhance this basic implementation as per your requirements!
