Good news for iPhone and iPad owners - the Christmas sales madness shows no signs of settling down, with Square Enix and Sega now getting involved.

Both companies have slashed the prices of the majority of their App Store libraries, with some very good offers to be had. Sonic the Hedgehog 4 Episode 1 and Chaos Rings, for example, have seen their largest price cuts since they were launched.

No need to rush purchasing these games: Sega's sale ends on the 3rd of January, whereas Square Enix’s comes to an end on the 5th.
