OK12 Bridge Inspector: Demo Guide for Philippines

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 Filipino Players Should Check

When playing OK12 Bridge Inspector in the Philippines, remember this is a demo with virtual currency, not a real-money casino. However, if you plan to switch to real play, you must verify the operator’s details. First, confirm they hold a valid license from PAGCOR, the national regulator, to ensure your rights are protected under Philippine law. Second, check which local payment methods are supported. While GCash and Maya are popular for online transactions in the country, OK12 may use different providers. Always check the cashier section on the operator’s website for the latest list. Third, ensure you are of legal age (18+) and play responsibly. Since this demo uses virtual coins, no PHP is lost, but real-money deposits vary. Look for clear terms on withdrawal times and fees. Finally, verify that the site is secure and that your data is protected. Do not assume all features shown in the demo are available in the real-money version. Always read the fine print before depositing your hard-earned pesos.

• Verify PAGCOR license on the operator’s official site.
• Check if GCash or Maya are currently supported for deposits.
• Confirm age requirements and responsible gaming tools.

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.
