OK12 Bridge Inspector Powers: Malaysia Demo Guide

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 Malaysian Players Should Check

Before engaging with OK12, verify the specific details for the Malaysian market. The primary currency for any potential real-money play is MYR (Malaysian ringgit), though the demo uses virtual units. Confirm whether the operator accepts local payment methods such as Touch 'n Go eWallet or DuitNow for deposits, as these are commonly used by Malaysians. You should check the payment section on OK12.info to see if these options are currently supported.

Additionally, check the licensing and regulatory status directly with the operator. Since gambling regulations vary, ensure OK12 is licensed to operate in your jurisdiction. For practical safety, always verify the terms regarding virtual coin expiration and confirm that the demo game is indeed free of charge.

• Check if Touch 'n Go or DuitNow are listed as valid deposit options.
• Verify the current licensing body regulating OK12 for Malaysian users.
• Confirm that the demo game remains free and does not require a deposit.

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.

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.
