The symbols include Pills, bombs, hearts, keys, coins, flies, and dollar signs. To get a pickup/fly, the slot's three symbols must match (e.g., three hearts). Coins, hearts and bombs can all appear two at a time.
It is possible to find Bombs (regular, troll, or 1+1 free), Hearts (half heart, full heart, soul heart or eternal heart, ), Keys (normal or golden), Coins (penny, nickel, or dime), Pills (any color), Flies (Pretty Fly or black enemy fly), and A Dollar. Walking up to the machine and bumping it will cost you one Penny, and roll the slots. Using the Tarot Card 'X Wheel of Fortune' will spawn a Slot Machine in the current room. The Slot Machine is similar to the Beggar in that the results are random.
