YSK: If you're playing mobile games with 5 lives and a timer to get them back you can set your phone time ahead to get full lives back quickly.

As the title poorly says, if you're playing those mobile games where they have five lives, and a timer to get them back, you can change your phones internal clock ahead however many hours to get the lives back.

Just go into your settings, date and time, set the time ahead, go back into the game, and then your lives will be back to normal.
Then just set your time back to normal and you're good to play again.

I'm not sure if this works for every game, but it has for the few I have tried. (Bubble Witch and some Futurama game.)
