Write the prompt around a playable rule
The example offers route choice and a visible countdown. A preview lets players compare the short risky route with the longer safe one. Keep stable and temporary stones distinct by shape and label as well as colour. The first level should use just one sinking stone to teach the timing rule.
Original concept prompt: “Create a short stepping-stone puzzle across a stream. The player moves one stone per tap toward a flag. Blue stones are stable; striped stones sink one turn after being stepped on. Show the sinking countdown and allow a route preview before starting. Add two possible paths, one short and one with a safe detour.” This is a recipe for an idea, not a claim that this exact game is already playable.
Play, observe and refine one thing at a time
Try the short path and count when the temporary stone sinks. Then choose the safe detour and compare its length. Check whether the countdown updates on the same move as the player’s step. If a route becomes impossible after a single action, add a restart or change the layout to leave a valid path.
Make a later level require a deliberate detour or a sequence of two temporary stones. Change layout first, then consider reducing preview information if the challenge is still trivial. Rehearse each level manually to make sure at least one solution exists. If the route feels like a memory test, keep the countdown visible throughout play.
Do not hide that a stone will disappear after the player commits to it. A route puzzle should test planning with known rules. Keep the flag visible and avoid placing the only goal behind a visual obstruction.
Playable reference for this prompt: Tide Trail. A paper boat drifts on its own through a canal network; tap junction switches in real time to route it past rocks, lock gates, whirlpools, tides, ferries and lightning to the lighthouse, collecting shells for stars across an 18-level journey map. Use this example to compare the proposed rules with a game you can try now. For your version, use this check: When should a striped stone sink?
Questions about stepping stone game prompt
When should a striped stone sink?
The recipe gives it a one-turn delay after use. Test moving away, waiting and stepping back so the countdown follows one understandable rule.
Why include a longer route?
It gives players a choice between efficiency and a safer sequence. Verify that both routes actually reach the flag under the same sinking rules.
