300SPINS™: Why We Record Every Spin
SlotWise uses FeatureMatch™ to organize the special features of every slot, giving readers a sense of each game’s character before they play. Features alone, however, cannot show what a session is actually like. For selected slots, we play 300 spins under consistent conditions and record every result. A 300SPINS™ review analyzes that observed play using eight metrics.
A closer look at the first session
The first 100 to 200 spins strongly shape how a player experiences a slot. That first impression changes with the frequency of wins, whether free spins appear, and whether the rewards are concentrated in a few large wins.
300SPINS™ records a little more of that initial experience. Three hundred spins cannot show everything a game might do. We are not trying to establish its theoretical probabilities from that sample. We aim to record a first session under consistent conditions and compare it with records from other slots.
Consistent playing conditions
To compare different games, we first need consistent playing conditions.
- Demo version: We play the demo so that our analysis is not tied to settings used by a particular casino or region. Some slots offer multiple RTP configurations.
- One session: We play all 300 spins in a single session. This does not assume that a slot has a supposed “flow.” It keeps play from different times and conditions from being mixed together and preserves one initial experience as a whole.
- Base bet: We keep the base bet and do not buy bonuses. Game conditions can vary with the bet amount, and players generally start with a low bet when trying a game for the first time.
Eight measures of the experience
We do more than record the 300 results. We organize them using eight metrics.
- Free Spin Hit Rate
- Free Spin Payout Multiplier
- Hit Rate
- Profit Hit Rate
- Max Multiplier
- Average Multiplier
- Free Spin Dependency
- Big Win Dependency
These measures show not only how often wins appeared, but also what kinds of wins produced the session’s results.
A growing basis for comparison
Chance can have a large effect on a single 300-spin session. But as sessions recorded under the same conditions accumulate across slots, they provide a common basis for comparison. The overall averages in the data collected so far also fall in ranges similar to those generally expected of slots.
300SPINS™ does not predict a slot’s future results or assign it a score. It is a review that makes every spin we actually played available and helps readers interpret that record alongside other games using the same criteria.
