Swift

About the science. Swift practises quick attention and ignoring distractions, and you will get faster at Swift by playing it. Games like this train the skills they practise; research has not shown that they raise general intelligence or improve everyday performance, and we don't claim they do. Play because it's fun, and track your own progress. More

Colours use a colour-blind-safe set, and every colour button shows its name. You can switch colour challenges off in Settings.
