Here's Find It Fast in action:
Colourful, note the 'Migital' branding, there are prompts when starting to sign into a Migital account and try other games, plus a few Symbian dialogs which are a little offputting (e.g. "Allow access to user data"); still, on with the game, I suggest 'Medium' or 'Hard' if you actually want a challenge.
The number to find is flashed up at the top of the screen and you then have to tap on it within 10 seconds - harder than it looks once your concentration starts to waver... On the 'Hard' level, each grid is completely filled with numbers
Sound effects are minimal and vibration effects are non-existent, leading me to suspect Migital of re-using code from other games here; somewhat annoyingly, the high score table doesn't distinguish between scores at the three difficulty levels, so 255 on Easy is worth as much as 255 on Hard, which doesn't seem fair...
It's fast, cheap and casual, but it will appeal to some, I'm sure. And hey, it's Fun Friday.... You can grab the free version here (presumably with ads) or buy the full game for £1 here in the Nokia Store.
