D’s Room Escape 4 (listed as D’s Room Escape 4 – Tyasitu) is a web-hosted escape puzzle in which you search a house and its hidden rooms for 20 coins. The complete route is: collect the four exterior coins, enter through the window with the axe, assemble the flashlight, solve the animal clue for the lockbox code 4241, open the safe, reveal the secret area, collect the final three coins from the baseball, and then choose one of four exits. The historical listing is from 2008 and names Japanese and English; it does not establish that “Ds” means a Nintendo DS release or that the original host is still playable today.
What is D’s Room Escape 4?
D’s Room Escape 4 – Tyasitu is identified in a historical escape-game listing as an online room-escape game. Its stated objective is to find 20 coins while interpreting environmental clues and using objects in the correct places. The listing names Japanese and English as the available languages and dates the entry to September 27, 2008. You can verify the period listing at EscapeJuegos’ September 2008 archive.

The title should not be treated as proof of a handheld-console edition. The available evidence describes a web game hosted by Tyasitu, not a Nintendo DS cartridge or download. Because the sources are historical, they also do not confirm current browser, plug-in, mobile, or desktop compatibility.
This guide follows the item route documented by the CheatBook walkthrough. If an object appears missing, check every location in the relevant section before assuming the game has failed to register a click.

What should I collect outside the house first?
Before entering, collect all four coins visible or reachable around the exterior. One is to the right of the house, another is in the mailbox, and a third is behind the doorstep. The fourth requires the axe: take the axe from the left side of the house and cut down the bamboo stalk on the left to reveal the coin.
- Search the area immediately to the right of the house.
- Open or inspect the mailbox.
- Look behind the doorstep rather than only clicking the front-facing area.
- Pick up the axe on the left, then use it on the bamboo stalk and collect the coin it releases.
Once those four coins are secured, use the axe on the cover over the front-window latch. Open the window and enter. This is the intended entry route in the walkthrough; trying to force another entrance before solving the interior sequence will not advance the puzzle.
How do I enter and gather the essential items?
Inside, make a methodical sweep before attempting the code. The walkthrough places several tools and clue objects in easy-to-miss spots:
- Take the spoon and the red box.
- Take the stick from the vertical part of the half-moon window.
- Take the flashlight from behind the cabinet.
- Shake the pillow to obtain the Japanese paper.
- Use the stick on the overhead shelf to bring down the lockbox.
- Collect the screwdriver.
The order is practical rather than a strict speedrun requirement. The stick is needed because the lockbox is out of reach; the screwdriver and spoon are needed to turn the red box into the flashlight lens; and the paper becomes readable only after the flashlight is assembled.
How do I assemble the flashlight and reveal the animal clue?
Use the screwdriver on the red box, then use the spoon to remove the lens inside. Fit that lens to the flashlight. Next, apply the Japanese paper to the square window and shine the working flashlight on it. The light reveals four animals, which are the symbols needed for the lockbox.
The guide identifies the animals, in order, as elephant, pig, alligator, lion. The accompanying paper clue is used with the top drawer to translate that sequence into digits. The walkthrough’s solution is 4241.

The guide author notes that the explanation involving the clue’s “round” letters is unclear. Treat 4241 as the documented solution rather than as a fully established linguistic rule. If the lockbox does not open, confirm that the lens is actually fitted to the flashlight, that the paper was applied to the square window, and that the animals were read in the displayed order.
What is the lockbox code in D’s Room Escape 4?
Enter 4241 into the lockbox. When it opens, take the key. This code is reported by the walkthrough for the elephant–pig–alligator–lion sequence; the available sources do not provide a second, independently verified code.
Use the key on the safe behind the hanging. Press the safe’s button so it turns green, then take the ruler. At this point, the walkthrough says you should have 17 coins. That intermediate total is useful: if you have fewer, inspect the indoor checklist below before moving on.
Where are all 20 coins?
The full coin route consists of 17 coins around the house and safe, followed by three inside the huge baseball in the secret area. The locations below preserve the walkthrough’s order while grouping the easily overlooked indoor spots.
Exterior coins
- To the right of the house.
- Inside the mailbox.
- Behind the doorstep.
- Released by cutting down the bamboo stalk on the left with the axe.
Indoor coins
- Behind the vase.
- Under the teapot.
- Behind the cups in the cabinet.
- Behind the bottom drawer; remove the drawer completely to expose the coin.
- Behind the cabinet.
- Under the pillow.
- Under the stack of pillows.
- On the underside of the lockbox.
- Under the incense burner.
- Under the lid of the tea box.
- Inside the lid of the tea box.
- Inside the safe door.
- Under the safe’s bottom shelf. This can be collected before pressing the green button or after leaving and returning.
Secret-area coins
- Inside the huge baseball; use the axe.
- Inside the huge baseball.
- Inside the huge baseball.
The three baseball coins are counted separately in the guide but share the same access method. If your counter is at 17 before opening the secret area, that is consistent with the documented route; the final three bring the total to 20.
How do I open the secret area?
After the safe button is green, use the axe on the wall to the left. The wall opens to a secret door. Beyond it is a huge baseball and a back door that the walkthrough describes as unlocked.

- Confirm the safe’s button has changed to green.
- Move to the wall on the left and use the axe.
- Enter through the revealed secret door.
- Use the axe on the huge baseball and collect all three coins inside.
- Note the back door for the ending choice.
The safe state is the important prerequisite. If the wall does not respond, return to the safe, press the button, and verify that the green state was registered before trying the axe again.
How do I get each ending?
The walkthrough lists four distinct ending triggers. They are determined by the exit or object you use after the main puzzle, so you can choose an ending without changing the coin route.

Use the axe on the window or door you used to enter. This is the first axe-based escape trigger listed by the guide.
End 2
Use the axe on the half-moon window. This is a separate trigger from the initial entry window.
End 3: Good End
Use the ruler to open the entry window or door. The ruler comes from the safe after you use its key and turn the button green. The walkthrough explicitly labels this route the Good End.
End 4: Tea Break End
Leave through the back door in the secret area. The guide calls this the Tea Break End.

To see every ending, finish the object-collection sequence once, then replay and change only the final exit action. The sources do not describe additional scoring, branching dialogue, or a different coin requirement for any ending.
What should I do if the puzzle will not advance?
Most apparent dead ends come from a missed interaction rather than a different solution. Use this checklist:
- Can’t enter: take the axe from the left, cut the bamboo for its coin, then use the axe on the cover over the front-window latch.
- Can’t read the paper: obtain the lens from the red box with the screwdriver and spoon, fit it to the flashlight, and shine it on the paper at the square window.
- Lockbox rejects the input: read the animals as elephant, pig, alligator, lion and try 4241. The guide’s explanation of the “round” lettering is uncertain, but its reported code is not.
- Safe does not open: use the key from the lockbox on the safe behind the hanging.
- Secret wall does nothing: press the safe button until it is green, then use the axe on the wall to the left.
- Coin count is short: check hidden surfaces, especially under both pillow locations, behind the bottom drawer, both sides of the tea-box lid, the safe door, and beneath the safe’s bottom shelf.
The archived sources do not document current browser requirements or a recovery procedure for a broken host. If the game itself no longer loads, that is an availability issue rather than a solvable in-game step; neither source verifies that the original page remains operational.
Does the game require all 20 coins to escape?
The historical listing describes finding 20 coins as the game’s objective, and the walkthrough accounts for all 20. The ending descriptions, however, are tied to four exit actions rather than a separately documented score screen. For a complete run, collect every listed coin before choosing an ending.

What is the shortest reliable route?
Use this compact sequence when replaying: four exterior coins and the axe; break the window latch and enter; collect spoon, red box, stick, flashlight, paper and screwdriver; make the lens and illuminate the paper; enter 4241; take the key; open the safe and turn its button green; take the ruler; collect the safe-area coin; cut open the left wall; open the baseball for three coins; then choose an ending.
That order minimizes backtracking while preserving the documented dependencies. The safe’s bottom-shelf coin is the only one the guide specifically says can be taken either before or after the green-button action.

What do the sources establish—and what remains unknown?
The evidence firmly supports the title variant, the Japanese-and-English language listing, the 20-coin objective, the 4241 walkthrough solution, the safe-and-ruler sequence, the hidden baseball area, and four ending triggers. It does not establish a Nintendo DS version, a current playable URL, modern device compatibility, or an official explanation for every letter-based clue.
Accordingly, use the route as a historical walkthrough rather than as a guarantee that the archived game will launch in a present-day browser. The guide is third-party, and its uncertainty about the “round” letter explanation is worth preserving instead of presenting a speculative decoding theory as fact.
Frequently Asked Questions
Is “Ds” in the title referring to Nintendo DS hardware?
The available listing identifies the game as “D’s Room Escape 4 – Tyasitu” and describes it as an online escape game. It does not document a Nintendo DS release, cartridge, or handheld-specific controls, so the abbreviation should remain unresolved.
Is D’s Room Escape 4 still playable online?
The surviving references are historical pages from 2008 and do not verify that the Tyasitu host still serves the game. They also provide no current browser or mobile compatibility information, so loading success cannot be promised.
Can I finish without understanding Japanese?
The listing names both Japanese and English, and the documented solution relies mainly on visual objects, item use, and the animal sequence. The guide does not explain which individual interface labels are localized, so language support may depend on the surviving version.
Why does the code clue mention “round” letters?
The walkthrough author flags that part of the explanation as unclear. The practical takeaway is to use the animal order and the reported numeric solution rather than treating an unverified letter-shape theory as an official explanation.
