by PlatinumFalls
"A light-hearted obstacle course (obby) where players sneak past an angry grandmother to steal cookies, featuring 19 skill challenges and an optional hard mode."

Grumpy Gran is a genuinely fun, story-flavoured obby that gives kids a satisfying skill challenge across 19 progressively harder stages. Navigating platforming sequences builds spatial reasoning, timing, and persistence — and the two difficulty modes give players a concrete goal to return to once they've mastered the first run. The cookie-heist premise is charming and age-appropriate, making it an easy confidence-builder for younger players new to obstacle courses.
What to watch out for
What to watch out for
With up to 10 players per server there is a light chat and social dimension, which carries the usual low-level stranger-contact risk inherent to any shared Roblox server. Like most Roblox experiences it likely offers some Robux-gated cosmetics or boosts, though these appear incidental rather than pay-to-win. There are no designed mechanics that incentivise grinding streaks or punish players for stopping — the experience has natural stopping points at the end of each run.
Parent tip
Challenge your child to beat it in Easy mode first, then set a family goal of conquering Hard mode together — it's a great way to share a play session and celebrate the moment they finally outrun Grumpy Gran!

Bottom line first
By default, Roblox allows unfiltered chat and friend requests from strangers. Enable Account Restrictions immediately — it takes 2 minutes and makes the platform significantly safer for children under 13.
Roblox is a platform of 40 million+ user-made games, not a single game. Quality, safety, and age-appropriateness vary dramatically between experiences. The LumiKin ratings above reflect individual experiences — the platform itself does not guarantee safety.
Robux is the in-game currency used across most popular experiences. Many games are designed around Robux spending — pay-to-win mechanics, exclusive cosmetics, and social comparison of avatar items are common. Set a clear spending policy before your child encounters the first purchase prompt.
The chat filter is imperfect. Children regularly find workarounds (number substitutions, deliberate misspellings). Monitor chat history periodically using the Parent PIN tools, and have an open conversation about what to do if someone says something uncomfortable.
Action: Roblox settings → Privacy → Account Restrictions (ON). This restricts chat, friend requests, and game access to a pre-screened age-appropriate set. Set a Parent PIN to prevent your child from disabling it.
