Online games will now be banned from giving players rewards if they log in every day, if they spend on the game for the first time or if they spend several times on the game consecutively. All are common incentive mechanisms in online games.

The new rules revealed on Friday are the most explicit yet aimed at curbing in-game spending. Besides banning reward features, games are also required to set limits on how much players can top up their digital wallets for in-game spending.

Games are also banned from offering probability-based lucky draw features to minors, and from enabling the speculation and auction of virtual gaming items.
