Slider

Slider, shown in the activity picker as "Guess the number", is an estimation activity. You ask a numeric question, and players slide a handle along a scale to lock in their answer. It's perfect for "how many…", "what year…" or "how tall…" style questions where there's one right number.

How players experience it

1. The question appears, along with a slider running across a range of values (for example 0 · 250 · 500).
2. Players drag the handle, or tap one of the value labels, to move to the number they want. The current selection is shown large above the slider.
3. When they're happy, they tap "Lock it in". The handle starts in the middle, so every player has to make a deliberate move.
4. Once locked in, they wait for the round to end, then see whether they were correct and how many points they earned.

Answering quickly and correctly is rewarded, so it plays much like a quiz round, just with a slider instead of answer buttons.

Setting one up as a host

When you add a Slider activity, you author the scale rather than a list of answers:

• Question. Type the numeric question you want players to estimate.
• Range (From / To). The lowest and highest values on the slider.
• Step. The gap between stops on the scale. For example, a step of 2 gives possible answers 0, 2, 4, and so on. A bigger step means fewer, more spread-out stops.
• Correct answer. The value that scores. It must land exactly on one of the stops; if it doesn't, Tikroo snaps it to the nearest valid stop and tells you which one.
• Accept answers within ±. An optional tolerance. Set this above 0 and any guess within that distance of the correct answer still counts as correct. Leave it at 0 to score only the exact stop.

A live preview shows every stop players will slide across, with the correct one highlighted.

Tips

• Choose a step that fits the answer. Too fine a step makes an exact hit unlikely. The slider caps the number of stops, so a very small step over a big range gets trimmed.
• Use the ± tolerance for estimation questions. For "how tall is the Eiffel Tower?" a little leeway keeps it fair while still rewarding good guesses.
• Keep the range sensible. A range that's much wider than the plausible answers just makes the slider harder to read.
