Diagonal Companions needs no APK
This game runs directly in the browser. The guide supplies no verified KM98 APK, package identifier, publisher signature, release number or store link. APK search wording is not proof of an application’s existence or identity.
No unknown-source permission, protection bypass, installation or device access is needed for this demo. A matching icon or version number does not establish a file’s safety. This game’s probabilities cannot validate external software.
Independent guide and Diagonal Companions
KM98 is a search name here without a confirmed commercial identity. This guide hosts its own Diagonal Companions game. It confirms no outside operator, affiliation, official domain, licence, payment service or app. Similar naming does not establish a shared publisher.

Captured settings and visible cell probabilities
While idle, choose hazard count and 10, 20, 50 or 100 virtual coins. Start shelves captures those settings and deducts one stake. Hazard count, stake and refill controls stay locked during the round. Collection is unavailable before the first safe reveal.
There is no Auto queue, timed crash or cashout threshold setting. Each click reveals one eligible cell immediately. Sound is optional. The game does not animate a moving hazard or require a reflex action; the hidden layout remains fixed.
Local storage and page requests
The game does not require a customer account, identity document or bank information. Local storage explains the balance and fractional carry, but does not imply that every request made while loading the page stays on the device.
Font, analytics, hosting and CDN requests may transmit technical information such as IP address and request details. This guide promises no complete anonymity, precise retention period, absence of profiling or third-party data-sale policy. Those questions require the providers’ own information.
Exactly one main-diagonal hazard with companions
Choose 3, 4 or 5 hazards on the 4×4 board. Exactly one hazard lies on the main diagonal from top-left to bottom-right. Every hazard, including that one, must have another hazard one row and one column away. Orthogonal adjacency alone does not qualify.
The anti-diagonal has no quota and separate diagonal-connected groups are allowed. Legal supports contain 6, 40 and 120 layouts for three, four and five hazards. Sample uniformly once; never relocate. A1 and D4 are safe in every supported mode: a corner hazard would require its diagonal neighbour, creating two main-diagonal hazards.
Guaranteed-safe cells do not increase the quote
A cell safe in every remaining layout has probability one. Opening it leaves the quote unchanged. Collecting after a guaranteed-safe first pick returns 0.97 times the captured stake, so it does not avoid the opening three-percent expected loss.
If no eligible uncertain cell remains, the current quote settles automatically even when unopened proven-safe cells remain. Proven hazards and quotes above 1,000× are disabled.
Optional use and personal limits
Participation is optional and offers no monetary prize. You may choose not to begin another round. Past outcomes do not make a fresh layout more favourable. A personal time limit does not change the layout distribution or conditional quote calculation.
This guide provides no clinical self-test, universal legal-age claim, confirmed external self-exclusion feature or promised transferable gambling skill. If play disrupts daily life, qualified local support may help. A free demo does not establish another product’s safety.

What makes a hazard layout legal?
Choose 3, 4 or 5 hazards on the 4×4 board. Exactly one hazard lies on the main diagonal from top-left to bottom-right. Every hazard, including that one, must have another hazard one row and one column away. Orthogonal adjacency alone does not qualify. The anti-diagonal has no quota and separate diagonal-connected groups are allowed. Legal supports contain 6, 40 and 120 layouts for three, four and five hazards. Sample uniformly once; never relocate. A1 and D4 are safe in every supported mode: a corner hazard would require its diagonal neighbour, creating two main-diagonal hazards.
How is the chosen cell priced?
After the opened safe cells are known, let N be the number of legal layouts consistent with that history. For an unopened cell let K be the number of those layouts where it is safe. Its safe probability is K/N. Each eligible cell shows that probability; it is not a generic remaining-safe-cells ratio. The quote starts at 0.97. A safe reveal changes quote q to q×N/K, using the probability of that very chosen cell before revealing it. A hazard ends the round with zero return. Collect returns captured stake times quote, with fractional carry. The identity (K/N)×(q×N/K)=q explains 97% expected gross return for choices using revealed information. This is not a win probability or a guaranteed session return.
Do guaranteed-safe cells remove the opening loss?
A cell safe in every remaining layout has probability one. Opening it leaves the quote unchanged. Collecting after a guaranteed-safe first pick returns 0.97 times the captured stake, so it does not avoid the opening three-percent expected loss. If no eligible uncertain cell remains, the current quote settles automatically even when unopened proven-safe cells remain. Proven hazards and quotes above 1,000× are disabled.
