In‑Depth Analysis of the Game’s Travel Simulation System and Item Mechanics

1. Is the Frog Actually Traveling?

The game implements a highly realistic travel simulation with rigorously designed routes, making the frog’s journey appear authentic despite being hidden from the player.

2. How Does the Frog Choose a Travel Path?

The world is divided into four regions (East, West, South, North), each represented by a connected undirected graph. The frog selects a region, then a start and goal vertex, and the travel route is a path between two vertices.

Graph visualizations of each region were extracted with Graphviz.

3. How Does the Frog Travel?

The carried items determine the maximum travel time (6‑72 hours).

Items also raise the initial stamina (base 100 %).

When traversing an edge, terrain and item attributes affect time and stamina consumption.

Encountered companions may join later trips and appear in postcards.

Road attributes give a chance to receive postcards.

If stamina runs out, the frog rests for 3 hours, restoring stamina to 100 % (rest time counts toward travel).

When the goal is reached or time expires, the frog returns home, possibly bringing back local specialties and collectibles.

4. How Is Time Calculated on Each Road?

Images illustrate the base and terrain‑adjusted time costs for each edge.

5. What If the Frog Runs Away From Home?

Without food, the frog will leave; placing food on the table brings it back within 5‑30 minutes.

6. Road Attributes

Terrain: normal, sea, mountain, cave.

Time cost: base + terrain bonus.

Postcard probability: varies per road element.

Companion encounter probability.

7. Item Effects

Five item categories are defined: Lunches, Lucky Charms, Props, Local Specialties, and Collectibles. Each item provides attributes such as maximum travel time (HP), stamina boost, random stamina boost, region bonus, movement speed, companion encounter boost, terrain‑specific postcard boost, and special FLAG effects.

8. How to Use Items Effectively

Choose a region by carrying region‑specific lunches or lucky charms; tickets can force a region.

Increase travel distance with high‑time items and reduce consumption with high‑stamina items.

Speed up traversal of certain terrains using items that grant terrain‑specific speed bonuses.

Raise companion encounter rates with matching items.

9. Which Postcards Can Be Collected?

Each road element has a defined probability to generate postcard components; the game combines background, foreground, frog pose, and companion pose into roughly 120 possible variations.

10. Which Local Specialties Can Be Brought Back?

Specialties are awarded only when the goal is reached; collectibles have a 15 % drop chance, while other items follow the probabilities shown in the accompanying table.

11. When Do Friends Visit?

Snails, bees, and turtles visit intermittently, staying for 180‑270 minutes. Bees require at least three collectibles, turtles need six.

12. What to Feed Visiting Friends?

Feeding yields three‑leaf clover and lottery‑ticket rewards; rare FLAG items increase these rewards.

13. How Fast Do Three‑Leaf Clovers Regrow?

Each of the 20 clovers regenerates independently, taking between 5 minutes (300 s) and 4 hours (14 400 s).

14. What Is the Chance of Getting a Four‑Leaf Clover?

After the tutorial, the first four‑leaf clover appears automatically; thereafter each three‑leaf clover has a 1 % chance to become a four‑leaf clover upon regrowth.

15. Lottery Ball Probabilities

White: 60 %

Blue: 27 %

Green: 9 %

Red: 3 %

Gold: 1 %

16. How to Earn Achievements?

During travel the frog sets various flags; the article lists the conditions that trigger each flag, noting that flag names have no effect on item drops or travel mechanics.

17. Is There a Free Way to Get Three‑Leaf Clovers?

The article ends with a playful hint that the answer is hidden.
