For players in the Philippines accessing the free demo, this means you can test how each Power level affects your virtual coin balance without risking real funds. Understanding these mechanics helps you decide which Power suits your play style best before you ever consider depositing.
The same ten fair link switches
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 PH Players Should Check Before Playing
When exploring OK12 Bridge Inspector in the Philippines, remember that this is a free demo site. You are playing with virtual coins, not real Philippine pesos (PHP). Before you dive deeper, you should verify how the operator handles real-money play. Check if OK12 supports popular local payment methods like GCash or Maya for deposits. Also, confirm the regulatory status. While PAGCOR is the national regulator for gambling in the Philippines, you must check if OK12 is specifically licensed or regulated by them. Look for this information in the footer or terms section. For safety, ensure you are using a stable internet connection and clear your browser cache if the demo lags. Always play responsibly, as demo results do not guarantee future real-money outcomes.
- Check for GCash or Maya support in the cashier.
- Verify PAGCOR licensing status on the operator's site.
- Use virtual coins to test Power 1, 2, and 3.
Count, square or cube
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.
| Bridge count | Power 1 score | Power 2 score | Power 3 score |
|---|---|---|---|
| 0 | 0 | 0 | 0 |
| 1 | 1 | 1 | 1 |
| 2 | 2 | 4 | 8 |
| 4 | 4 | 16 | 64 |
These powered scores are not multipliers. Each is divided by the mean for its Power and multiplied by 0.96 to obtain the gross multiplier.
Graph examples across all Powers
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.
Changing Power cannot turn a graph with zero bridges into a paying graph. Nor does it change the probability of drawing a chain, cycle or isolated vertex.
Controls before and during a draw
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.
Expected return and settlement
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.
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.
A local wallet, not a game catalogue
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.

Frequently asked questions
Does Power 3 make bridges more likely?
No. Every Power samples the same 1,024 equally likely graphs. Power changes the bridge-count payout formula, not the graph probabilities.
Are the squared and cubed scores the amounts paid?
No. The powered count is normalized by its Power mean and multiplied by 0.96. The resulting multiplier is then applied to the captured stake, with carry and integer credit.
Can I change Power during the draw?
No. Power and stake are captured at the start and locked until settlement. You can choose another Power for the next draw.
Does OK12 use Philippine pesos (PHP) in the demo?
No, the demo uses virtual coins. Real-money play may use PHP, but you must check the operator's cashier section to confirm currency options and exchange rates.
Is OK12 regulated by PAGCOR?
It depends on the operator. You should check the 'About Us' or 'Licensing' page on OK12's official site to see if they hold a valid PAGCOR license for Philippine players.
