Although its not a cheat, more of a hint. I found the casino level to be
the worst of all the levels. The handling ont he Bingo tables is really
bad. But this should help u save lives.
On the 2nd zone of the casino levels at the very last table where u sort
of enter a slide and u go through a swirly blue and yellow tunnel. This
table is full of pot holes and alot of jumps. When going round corners u
usually find a pot hole. dont fight against it just move witht he
rolling. you'll find it is safer than usual.
Also before u enter the swirl blue tunnel u can save many many lives
here (i died alot on the tables) instead of jumping onto it and all your
characters going down. get the speed character selected (sonic, shadow,
amy, espio)and move slowly forward into the pipe. you shoudl find if
done right that only the speed guy goes down. ow when u fall off the
table you will automatically be selecte with a new characters and the
speed one will appear next to them as though he were knocked out. Keep
repeating the process till u work your way down the table.
