Stop learning the periodic table by rote!“Periodic Table Lottery” combines lottery-style gameplay with the periodic table. Place bets, earn rewards, complete level objectives, and see how far you can go!Choose your betting group from groups (columns), periods (rows), or element categories. In each round, 10 elements are randomly drawn—if any of them belong to your selected group, you win a corresponding payout. (The smaller the group, the higher the odds!)
