A giant game of Tetris has been played on the side of a Philadelphia skyscraper to mark 30 years since the game was developed.
Hundreds of LED lights were attached to the Cira Centre building by organiser and game designer Frank Lee, who previously holds the Guinness World Record for the largest architectural game display for a similar event, Pong in 2013.
Game designer Lee said the skyscraper Tetris project "was a personal love letter to the games I loved as a child."
Apple will refund at least $32.5 million (£19.8 million) to US consumers whose children made in-app purchases without their consent, the US Federal Trade Commission announced.
Under the terms of the settlement, Apple will also be required to change its billing practices to make sure it has obtained "express, informed consent from consumers" before charging them for items sold in mobile apps.
FTC chairwoman Edith Ramirez said the complaint alleges that Apple did not inform account holders that entering their password would open a 15-minute window during which unlimited charges could be made with no further action by the account holder.
Games trade body Ukie said all its members "take their responsibility to their players, particularly children, very seriously".
Ukie chief executive Jo Twist said:
We welcome any guidance from the OFT [Office of Fair Trading] to clarify how they are interpreting the law and shall be taking our time to digest the proposed guidelines before responding fully to the OFT’s consultation.
The online games app industry has been warned by the Office of Fair Trading of "potentially unfair and aggressive commercial practices" that could target "susceptible" children to pay to continue playing 'free' web and app-based games.
