Noma ubani othola “isethi” lapha uzothola ibha kashokoledi kimi.
I-Set igeyimu ehlakaniphile esiyidlalile cishe eminyakeni emi-5 edlule. Ukumemeza, ukuklabalasa, inhlanganisela yezithombe.
Imithetho yalo mdlalo ithi yasungulwa ngo-1991 yisazi sofuzo uMarsha Falco, ebhala amaphuzu ngesikhathi socwaningo lwesithuthwane kubelusi baseJalimane ngo-1974. Kulabo ubuchopho babo bukhathele ngokwanele ngezibalo, ngemva kwesikhathi esithile kuvela izinsolo zokuthi kukhona okunanelayo lapha nge-planimetry nokudweba imigqa eqondile ngokusebenzisa amaphuzu. (Uma kunikezwe amakhadi amabili, kunekhadi elilodwa futhi elilodwa kuphela elingena kwisethi efanayo nawo.)
U-Marsha Falco ubonakala ebuza: “Awuzange uthole “isethi”?”
Khumbula imithetho
Isethi ingumdlalo wamakhadi. Wonke amakhadi anemingcele emine, ngayinye ethatha amanani amathathu (ingqikithi 3 x 3 × 3 × 3 = 81 amakhadi).
Izinhlobo namanani amapharamitha ami kanje:
- umfanekiso ::= i-ellipse | gquma | "snot"
- umbala ::= obomvu | okuluhlaza | i-violet
- gcwalisa ::= mhlophe | imidwa | okuqinile
- ubuningi ::= 1 | 2 | 3
Inhloso yalo mdlalo siqukethe ukuthola inhlanganisela ekhethekile amakhadi amathathu. Amakhadi amathathu abizwa ngokuthi “isethi” uma, ngemfanelo ngayinye yamakhadi amane, wonke afana, noma konke ezahlukene.
Ngamanye amazwi, singasho ukuthi amakhadi amathathu ngeke enze isethi uma amakhadi amabili enenani elilodwa lepharamitha, kanti eyesithathu inomunye. Ungabona ukuthi kunoma yimaphi amakhadi amabili kuhlale kuneyesithathu (kanye neyodwa kuphela) azoba yisethi.
Ukuqhubeka komdlalo: Umethuli ubeka amakhadi ayi-12 etafuleni. Uma othile ethola isethi, uyamemeza "Setha!" abese ethatha ngokuthula amakhadi akha isethi. Uma kungekho sethi emakhadini abekiwe (okungenzeka, kubonakala sengathi akukho), umethuli ubeka amanye amakhadi amathathu.
Inombolo enkulu yamakhadi ngaphandle kwesethi ama-20. Umjikelezo uyaqhubeka kuze kube yilapho idekhi iphela. Oqoqa amasethi amaningi uyawina.
Ongoti bezibalo babambe iqhaza futhi bethula inhlanganisela yamakhadi angama-20. Noma ubani ozibheka njengo-Chuck Norris angakhohlwa lesi sithombe futhi azame ukudlala i-solitaire ngaphandle kwesethi eyedwa.
Noma hlola ukuze ubone ukuthi kusekhona “isethi” lapha?
Amakhadi angama-20 angenayo isethi
Kuhle ukuhlola ukuthi akukho "okubekwe ngombala".
Amakhadi afanayo, kodwa indawo ibonisa ukuthi iphethe amasethi ngokuya ngepharamitha "yokugcwalisa".
Kubalwa.
Ngokwezibalo.
Akukho okusethiwe ekuhlukaniseni izici.
Vula inkinga engaxazululiwe kuzibalo
Ingakanani inombolo enkulu yamakhadi ongayibeka ngaphandle kokuthola "isethi" eyodwa? Isibonakaliso sinezincazelo ezintathu.
“nophawu” olu-1 - amakhadi ama-2
2 izimpawu - 4 amakhadi
3 izimpawu - 9 amakhadi
4 izimpawu - 20 amakhadi
Izimpawu ezi-5 - amakhadi angama-45
Izimpawu ezi-6 - amakhadi angama-112
7 izimpawu - xs
Kuthiwani ngo-“n→∞”?
