On the hottest weekend of the year, these are the two purchases parents weigh. They are not the same product in different sizes — one is a piece of ground-based infrastructure and the other is an activity you put on the grass.
The spec sheet

| Published age range | 5 to 12 | 6 to 12 |

| Ground needed | Long, flat, stone-free run plus run-out | A flat patch |
The decision
What decides it
The run-out, not the slide
An 18 foot slide needs considerably more than 18 feet of lawn, because a child leaves the end of it at speed. Anything hard within that overrun — a fence, a patio edge, a tree — is the reason to size down or choose differently. The full safety brief is in slip and slide safety.
Number of children
A slide is one child at a time per lane and a queue behind it. A spray game is published for 2 to 4 at once and has no queue at all, which at a party of small children is usually the better shape.
What it does to the lawn
A slide is a sheet of plastic sitting on grass with water running under it for hours. Move it between sessions or expect a yellow stripe — see yard games and your lawn.
The other side
Where to buy the other one
The card at the top of this page covers one side of the comparison. This is our current pick for the other, ranked on published specifications rather than on play we have not done.
Best splash mat game
GoFloats Splash Off Water Spray Splash Mat Game
GoFloats
A spin-and-twist floor game on a raft-grade vinyl mat with a water valve on the hose connection, published for 2 to 4 players aged 6 to 12 — a sprinkler with rules.
Skip this if
Skip this for toddlers. GoFloats publishes an age range of 6 to 12, and a spin-and-twist game on wet vinyl is a slipping game for anyone smaller.

Why you can check our work
We have not played these. Every figure above is copied from a manufacturer's published listing or a governing body's published rules, and named so you can verify it. Where a maker publishes nothing, the field is blank rather than filled in. How we pick explains the whole method, including what would change a recommendation.
