Though the Dr Watts Up is listed as having 243 paylines – i.e. any three like combinations landing in the first three reels represents a win – the player wagers in increments of 30, from 30 to 600 coins possible to bet per spin.
A special scatter – some kind of mutant white mouse, it seems – appears only in the first, third and fifth reels. When three hit on a single spin, the “Laboratory Bonus” round begins. This video bonus round is of the “pick ‘em” variety, but it’s a bit more involved … and potentially lucrative. Select two “chemical tubes” of those displayed on the new screen and the virtual machine spits out a prize amount, asking the player if she/he wants to try again. Up to three attempts are possible.
The more standard scatter is the atom symbol; this is worth 10, 15 or 20 free spins when three, four or five, respectively, land on a single spin. Top jackpot payout in Dr Watts Up is 480,000 coins (or $96,000).
