Flat-Top Slot

Slot Types

A slot machine with a fixed, non-progressive top jackpot amount. The maximum payout does not change regardless of how many times the machine is played or how much coin-in it receives. Flat-top machines typically offer higher base-game RTP (Return to Player) percentages than progressive machines because no portion of each wager is diverted to fund a growing jackpot. From an operational standpoint, flat-tops provide more predictable and stable hold percentages over time, making them easier to forecast for revenue planning.

In practice

Sometimes called “straight slots” or “regular slots” in older casino parlance. Most video slots on the floor are flat-tops.
