Potions are tumbling off the shelves of a wizard's laboratory, and it is up to you to stop the shelves overflowing. In Wizards Lab, stacks of three coloured vials fall into the well. You slide them sideways and shuffle their order so that three or more of one colour line up across, down or diagonally, and vanish. Mixed in with the potions are magical reagents, such as fireballs, lightning bolts, bombs, stars and prisms, which go off when they clear and can set each other off in long chain reactions.

Objective Match three or more vials of the same colour in a row, column or diagonal to clear them, and keep the well from filling to the top. Controls • Joystick in port 2 • Left / Right: move the falling stack • Up: rotate the colours in the stack • Fire: rotate the other way (and start the game) • Down: drop faster • P: pause (keyboard) Tips • Tiles match by colour; the symbol on a tile decides what it does when it clears. • Fireball: clears every tile of its colour. Bolt: clears its whole row and column. Bomb: clears the 3×3 around it. Star: doubles the cascade's score. Prism: matches any colour. • A reagent caught in another reagent's blast goes off too. Save them up for big chains. • Every 30 tiles cleared raises the level and the speed. Modes • 1 player, endless, with a session high score
