Madder Scientist Slots
Madder Scientist slots is a 3D slot with a movie-quality opening where you watch what too much power can lead to. In the game's prequel, Mad Scientist slots, Dr. Prescott learned how to turn items into gold. He's back with plans to do even better.
In this 5 reel bonus slot, there are four bonus features. With the variety of instant cash prizes and free spins bonuses, it's not surprising to see this 3D slot on the list of games popular with slot game winners.
Here's What You Can Win in the Base Game
To determine how much you can win, take all of these payouts as shown on the paytable in Madder Scientist. You win payouts with three, four, or five matching symbols on an active line with several of the symbols. You can win with two or more with the Light, Bunny, Assistant, or Dr. Prescott. You'll multiply them by your coin value and then the coins per line.
- Danger High Voltage - 10x, 20x, or 40x
- Cells - 20x, 40x, or 75x
- Test Tubes - 30x, 60x, or 100x
- Microscope - 40x, 75x, or 200x
- Light - 5x, 50x, 100x, or 300x
- Bunny - 5x, 60x, 150x, or 400x
- Assistant - 10x, 100x, 250x, or 500x
- Scientist Doctor Walter Prescott - 15x, 200x, 250x, or 500x
If you bet 5 coins on the 30 paylines and have the coin value set at 10 cents, you would win $5 with three Danger High Voltage symbols ($0.10 coin value times 5 credits per line times 10x from the paytable = $5). On a max bet, the highest payout is $2,500 with the Assistant or Dr. Prescott.
Four Bonus Features Await Players
Madder Scientist slots has three bonus symbols. Each triggers a special bonus round that may award cash or free spins.
The Carrot Bonus - The Carrot is a bonus symbol that triggers the Carrot Bonus Round. In this game, mix potions together to create a concoction you'll use on the carrot. That concoction could turn the test carrot into a valuable one. For example, our choices of purple and orange turned the carrot into silver and paid $250 on a $15 wager.
The Click Me Bonus - The Click Me bonus round starts when you get Click Me Beaker symbols on the first, third, and fifth reels. You're shown a selection of beakers. Pick them until you find the one that says "Collect." Each beaker awards cash or free spins that are awarded when you find "Collect."
Wild Switches - Get three and win a set number of free spins with one Wild Reel frozen on the screen. You can add additional free spins to this by getting another Wild Reel with the +1 Spin message.
There's one more bonus feature in the slot game. After a spin, all five reels show a "Respin" message at the bottom. You can pay a fee and spin that reel again. This is useful with the bonus symbols. If you have two, you can spin that chosen reel to try to land the third symbol and trigger the bonus round.
Getting Started
Before you spin the reels, activate the number of paylines and bet up to 5 coins per line on them. There are 30 lines in all. Next, choose your coin value (1 penny to $1), leading to a max bet of $150. If you want to use the "Max Bet" option, set your coin value first and the computer handles the rest. Max Bet sets the lines to all 30 and puts you at the bet per line of 5.
You're able to adjust game controls through the Game Settings menu. Turn on Turbo Play if you want. Turn the background music on and off, turn on the sound effects, and turn Expandicon animations on and off as you wish. Note that if you turn on Turbo Play, Expandicon is automatically turned on.
Place your wager, set the game controls to where you want them, and spin the reels. See what happens when you play Madder Scientist.
