For readers in Malaysia, understanding the local context is key. While the demo uses virtual coins, real-money play may involve MYR. Always verify current payment methods and regulatory status directly with the operator, as gambling laws in Malaysia are tightly restricted.
Ten switches and five vertices
Bridge Inspector draws an undirected graph on five vertices, labelled 1 to 5. Ten independent fair switches choose the ten possible links, one for each pair of vertices. Each link is equally likely to be present or absent, so all 1,024 graphs are equally likely. A bridge is a present link whose removal increases the number of separate connected components. Isolated vertices count as components too.
What Malaysian Players Should Check
When engaging with OK12 in Malaysia, ensure you understand the local landscape. Although the demo is free, real-money transactions typically use MYR. Verify if the operator accepts Touch 'n Go eWallet or DuitNow, as these are common local methods. Check the official site for current licensing, since Malaysia’s gambling regulations are strict. For safety, use a secure internet connection and confirm the site’s SSL certificate. Always play responsibly, as you are over 18.
- Confirm if Touch 'n Go eWallet is supported.
- Check if DuitNow transfers are available.
- Verify the operator’s license status.
Three Powers, one graph distribution
The score is the number of bridges, from 0 to 4. Power 1 uses that count, Power 2 its square, and Power 3 its cube. The gross multiplier is 0.96 × that powered score divided by its own average over all 1,024 graphs. All Powers draw from the same graphs with the same probabilities; the selected Power changes the payout mapping, not the chance of a particular graph. No bridges means zero return in every Power.
Each Power has exactly 96% expected gross return before whole-coin wallet credits and carry. That average follows from applying the 0.96 factor to a powered score normalized by its own mean. It is not a promised return for a round or session. A gross return includes what is paid back from the stake, rather than being additional profit. Integer credits and carry mean that an individual wallet credit need not equal 96% of its stake.
What a bridge looks like
A chain with only links 1–2, 2–3, 3–4 and 4–5 has four bridges: removing any one splits the chain. A five-vertex cycle has no bridges because another path remains around the cycle. A single link 1–2 has one bridge even though vertices 3, 4 and 5 are isolated. A graph with no links also has no bridges and returns zero.
On the result diagram, solid links are present, amber links are bridges and dashed links are absent. A link in a cycle is not a bridge merely because it is visible or long.
Choose one draw at a time
Choose a stake of 10, 20, 50 or 100 and a reward Power of 1, 2 or 3 before pressing Draw link switches. A fresh page selects stake 20 and Power 1, with sound off. The chosen stake is deducted once at the start, and both stake and Power are fixed for that draw. Stake, Power, draw and restoration controls are locked until settlement; sound remains available. There is no early collection or automatic queue.
Wallet, remainder and reload
A new wallet starts at 1,000 free virtual coins. Settlement multiplies the captured stake by the full multiplier and adds the saved fractional remainder. Only the whole-number part is credited to the wallet; the new remainder is saved for a later settlement and is never credited separately. The multiplier shown on screen is rounded to four decimal places, but the calculation uses the full value. A zero return credits no coins and retains the existing remainder.
Restore balance is available only when no draw is active and the balance is below 10. Pressing it sets the wallet to exactly 1,000; it does not add 1,000 or run automatically. The fractional remainder is preserved. A balance of exactly 10 is not eligible.
The wallet is saved when the stake is deducted and again when the result is credited. Reloading during an unfinished draw loses that draw without refund or resume, so its already deducted stake stays deducted. The saved wallet, including zero, and fractional remainder remain if browser storage is retained. Reload returns stake to 20, Power to 1 and sound to off; the result meters show a dash.
Scope, storage and adult use
This independent OK12 guide explains its own free browser demo. No outside operator, business ownership, licence, official account address, payment service or app has been established here. A matching name or search result does not verify an outside service or connect it to this demo.
The browser stores the virtual wallet and a separate fractional remainder in localStorage for this site. The page also requests Google Fonts resources and loads the Statinside measurement script for counter ID 44, with a measurement image when JavaScript is disabled. These identified requests are not a complete network audit. Local storage and the lack of a login do not establish anonymity or promise that no personal data are processed.
The guide is intended for adults aged 18 and over. That label does not enforce an age check or establish local legality. Virtual coins have no cash value, cannot be withdrawn and are not prizes.
Frequently asked questions
Does a connected graph always pay?
No. A connected cycle can have no bridges and return zero. The score counts bridges, not simply whether the graph is connected.
Can I collect before the result?
No. Each draw uses one captured stake and settles once its graph is shown. There is no early collection or automatic queue.
What happens if I reload during a draw?
The unfinished draw cannot resume and its deducted stake is not refunded. The saved wallet and carry remain if storage is retained; stake 20, Power 1 and sound off are restored.
Is OK12 legal in Malaysia?
Gambling is tightly restricted by national law in Malaysia. While some forms are permitted, others are not. You must check the latest regulations and OK12’s specific licensing status directly with the operator before playing.
How do I check payment methods?
Visit the OK12 website’s banking section. Look for Touch 'n Go eWallet or DuitNow options. If not listed, contact their customer support to confirm if these Malaysian payment methods are currently supported.
