ThinkFun Rush Hour Junior Review
Reviewed from ThinkFun's published specifications and the arithmetic on them. We have not played it, and we say so.
By Sawyer V. · Published
The short answer
Rush Hour Junior is worth it as a first logic game and not as the main present. ThinkFun publishes 40 challenges from easy to expert, an ice cream truck, 15 blocking vehicles and a travel bag, single player, no batteries, rated 5+. Forty is a real number, and a determined child will finish it.

What we can tell you, and what we cannot
We have not played it. No lab, no samples, no test children, and no star rating on this page or in its structured data.
ThinkFun’s published challenge count, contents, player count and age rating we can compare across the category. Whether challenge 31 is the one that finally stumps a particular six-year-old, we cannot.
The specification that decides it
The arithmetic
Rush Hour Junior, published
| Challenges | 40, easy to expert |
|---|---|
| Contents | Ice cream truck, 15 blocking vehicles, 40 challenge cards, travel bag |
| Players | 1 |
| Batteries | None |
| Stated age | Ages 5+ |
| Step up | The full Rush Hour at 8+, same idea, harder cards |
What the numbers mean in practice
Forty is genuinely forty. Single-player puzzle games publish their own expiry date, and this is the shortest on the site. That is not a flaw — it is a reason to buy it as a stocking gift rather than the main present.
The grid does not end with the cards. Children invent their own jams once the deck is done, and a parent can set new ones in seconds. Nothing in the box prompts that, so it is worth saying out loud.
No batteries, no consumables, no reading. The three properties that make a five-year-old able to play unaided.
The travel bag is not a throwaway. A single-player game with a bag and no loose marbles is one of the few genuinely good car and waiting-room toys.
One player means one player. ThinkFun publishes a single-player game, which is the point at this age: a five-year-old can play it without an adult taking a turn, and there is no argument about whose go it is. It is also why it does nothing at all for two siblings on a wet afternoon.
Who should skip it
A child already six or seven. IQ Puzzler Pro publishes 120 challenges from 6, and Kanoodle publishes 200+ from 7.
Anyone buying the main present. Forty challenges is a supporting gift.
A child who wants something to happen. Nothing moves, lights or falls here. Gravity Maze at 8+ is the one where a marble proves the answer.
Say the unwelcome thing
Do not buy it and the full Rush Hour together
ThinkFun publishes the full Rush Hour at 8+ as the same idea with harder cards. Bought together, the junior set is finished in a fortnight and the older set sits waiting three years. Buy the one that matches the child now.
Forty challenges, against the rest of the shelf
Single-player logic games publish their own length, which makes this the one category where you can compare value before buying.
The arithmetic
Published challenge counts, single-player logic games
| Rush Hour Junior | 40, easy to expert |
|---|---|
| Gravity Maze | 60, beginner to expert |
| Code Master | 60 levels, beginner to expert |
| IQ Puzzler Pro | 120, across 2D and 3D modes |
| Kanoodle | 200+, across flat 2D and 3D pyramids |
That table is the argument for and against this set at once. Forty is the smallest number on it — and every other game in the list publishes a starting age of 6, 7 or 8, so at five there is nothing else to buy.
The other four are all still there in a year. Buying Rush Hour Junior at five and IQ Puzzler Pro at six is a better sequence than buying the 120-challenge set early and watching it sit unopened.
The travel bag is not a throwaway either. A single-player game in a bag, with no marbles and no batteries, is one of the very few genuinely good things to hand a five-year-old in a car or a waiting room.
Where it sits
Rush Hour Junior appears in choosing a first logic game and STEM games for one player, and in small STEM gifts that travel.

1. The product
ThinkFun Rush Hour Junior
ThinkFun · 76583 · maker rates it 5+
40 graded challenges in a grid a five-year-old understands in one sentence: get the truck out.
- Challenges
- 40, easy to expert
- Contents
- Ice cream truck, 15 blocking vehicles, 40 challenge cards, travel bag
- Players
- 1
- Batteries
- None
ThinkFun publishes 40 challenges across four difficulty tiers from easy to expert, an ice cream truck, 15 blocking vehicles, 40 challenge cards and a travel bag, single player, with no batteries, rated ages 5+.
The goal explains itself. No reading is needed to understand that the truck has to reach the exit, which is why this works at five where most logic games start at six or eight.
Self-checking is the other reason it suits this age: the truck either gets out or it does not, so nobody has to mark the work. A child can take it to another room and simply play.
Replay signal
- Open-ended or one-shot
- Finite — 40 challenges
- Does anything run out
- The cards end; the grid does not, and children invent their own jams
- Room to grow
- Steps up to the full Rush Hour at 8+, same idea with harder cards
Why we say so: ThinkFun publishes 40 challenges across four difficulty tiers and a travel bag. Forty single-player puzzles is a school holiday, not a year — which is the honest framing for a gift-buyer.
What’s wrong with it
Forty challenges is the lowest published count of any logic game on this site.
| Challenges | 40, easy to expert |

2. The much longer ladder
Kanoodle
Educational Insights · Kanoodle · maker rates it 7+
200+ puzzles across flat 2D and 3D pyramid formats, in one compact case.
- Puzzles
- 200+
- Formats
- Two — flat 2D puzzles and 3D pyramids
- Pieces
- Connected-bead puzzle pieces
- Players
- 1
Educational Insights publishes 200+ puzzles across two formats — flat 2D puzzles and 3D pyramids — using connected-bead pieces, single player, no batteries, rated 7 and up.
Two hundred against forty is the comparison that matters if the child is already seven. See Kanoodle vs IQ Puzzler Pro.
Replay signal
- Open-ended or one-shot
- Finite, but 200+ published puzzles is the largest count on this site
- Does anything run out
- Nothing runs out; the booklet is long enough to feel endless
- Room to grow
- 2D first, then the 3D pyramid set, which is a genuine step in difficulty
Why we say so: Educational Insights publishes 200-plus puzzles across 2D and 3D formats from one small case. Two hundred is roughly three times what a typical single-player logic game ships with, which is why this one survives a long car journey and a wet week.
What’s wrong with it
Rated 7+, two years above Rush Hour Junior's floor.

3. The wider age range
SmartGames IQ Puzzler Pro
SmartGames · SG455 · maker rates it 6+
120 challenges across 2D and 3D modes from 12 pieces, with solutions in the booklet.
- Challenges
- 120, across 2D and 3D modes
- Contents
- Compact board with a transparent lid, 12 puzzle pieces, challenge booklet with solutions
- Players
- 1
- Batteries
- None
SmartGames publishes 120 challenges across 2D and 3D modes, a compact board with a transparent lid, 12 puzzle pieces and a challenge booklet with solutions, single player, rated 6 to adult.
Three times the challenge count of Rush Hour Junior, in a case that is its own board. For a six-year-old this is usually the better buy.
Replay signal
- Open-ended or one-shot
- Finite, but 120 challenges is roughly double what most single-player puzzle games ship with
- Does anything run out
- The booklet ends. The pieces do not
- Room to grow
- The same 12 pieces run 2D and 3D challenge sets, so the difficulty ceiling is well above the entry point
Why we say so: SmartGames publishes 120 challenges across two modes from a single 12-piece set. Twelve pieces generating 120 published problems is the best challenge-per-component ratio of any logic game on this site, and it is the reason this one travels well and lasts.
What’s wrong with it
Rated 6+, so it waits a year after Rush Hour Junior works.
| Challenges | 120, across 2D and 3D modes |
|---|---|
| Contents | Compact board with a transparent lid, 12 puzzle pieces, challenge booklet with solutions |
| Players | 1 |
| Batteries | None |
| Stated age | Ages 6 to adult |
| Travel case | Yes — the board is the case |

ThinkFun Gravity Maze
ThinkFun · 44001006 · maker rates it 8+
The same maker's marble logic game, published three years later.
- Challenges
- 60, beginner to expert
- Contents
- Game grid, 9 towers, 1 target piece, 3 marbles, 60 challenge cards
- Players
- 1
- Batteries
- None
ThinkFun publishes Gravity Maze with 60 challenges from beginner to expert, a grid with 9 towers, 1 target piece and 3 marbles, single player, no batteries, rated 8+.
Often bought alongside Rush Hour Junior for a younger sibling. At five it is three years early, and the marbles are a small-parts problem in the same room.
Replay signal
- Open-ended or one-shot
- Finite by design — 60 challenges, and a determined child will finish them
- Does anything run out
- Nothing physically runs out, but the challenge cards do end
- Room to grow
- The towers can be used freely once the cards are done, though nothing in the box prompts that
Why we say so: ThinkFun publishes 60 challenges and a fixed component list. Sixty is a real number with a real end, and single-player puzzle games are the category where that matters most — better to know before you buy it as the main present.
What’s wrong with it
Rated 8+, with small towers and marbles.
| Challenges | 60, beginner to expert |
|---|---|
| Contents | Game grid, 9 towers, 1 target piece, 3 marbles, 60 challenge cards |

| Batteries | None |

| Consumables | None |

We are not putting a buy button on this one. It is easy enough to find if you want it anyway — but we would rather send you to something that gets played with twice.
