Innovative puzzler Scribblenauts Remix has added a new speech recognition feature for iPhone 4S users.
The type-what-you-want title now allows players to shout out words instead via the Scribble Speak feature.
Scribblenauts sets players puzzles with multiple solutions. Each level is solved by using an almost-endless array of summonable in-game items.
Remix is a blend of new levels and classics from the first two original Scribblenauts games on DS, which together sold 2.5 million copies.
Released for £2.99, it's now a pound cheaper at £1.99 on iPhone and iPad.
