Responsible Use of the OK12 Demo

Understand the graph result

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.

A result with no bridges returns zero, even if the graph is fully connected. A winning draw does not predict the next result.

Set voluntary limits before drawing

Choose a personal limit for time or virtual coins and stop when you reach it. Stakes are 10, 20, 50 and 100. A larger stake scales the gross return and the amount at risk in that draw. There is no automatic queue, so leave the controls idle instead of starting another draw when it is time to stop.

Break after settlement

There is no early collection or pause-and-resume control. Let the current draw settle before leaving. Reloading during an unfinished draw does not refund its deducted stake. The demo has no enforced session timer or account-level self-exclusion system; use your own time reminder if helpful.

Power is not a loss safeguard

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.

Changing Power alters payouts but does not enforce a session budget, prevent zero returns or guarantee recovery of earlier losses.

Restoration and browser data

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 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.

Free restoration changes the wallet rather than erasing past results. Consider stopping instead of restoring if you have reached your personal limit.

Audience and finding support

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.

If play feels difficult to control or affects daily life, step away and seek appropriate local qualified help. This demo does not provide treatment or demonstrate that play trains safer behavior.
