Tressette a chiamare

I-algorithm yomdlalo isesigabeni sokuqala sentuthuko futhi izothuthukiswa kusuka enguqulweni iye enguqulweni, kepha kufanele ivele ivumele ukudlala okuthile.
Abadlali abathathu, amakhadi ayi-12 lilinye kanye namakhadi ama-4 ukwenza "intaba" embozwe etafuleni. Umdlalo uqala ngesigaba sesimemezelo. abadlali bakhuluma ngokulandelana, futhi ngokususelwa kumakhadi asezandleni kufanele banqume ukuthi bayawuvula yini umdlalo, baphakamise ibhidi yokuvula noma basonge. Izimemezelo ezingaba khona yilezi:
"CALL": umdlali uthi uzodlala ngokubiza ikhadi alilahlekile (ngokuzibophezela ngokulandelana: ezintathu, ezimbili, i-ace, njll.). Uma ethola ikhadi kumphikisi, kufanele alibuyisele ngokuthanda kwakhe.
"KUPHELA": umdlali uthi uzodlala ngaphandle kokucela amakhadi kepha esebenzisa intaba kuphela.
"SOLISSIMO": umdlali uthi uzodlala kuphela namakhadi asesele ekhona, ngaphandle kokuthatha intaba.
Umdlali onqobayo umzuliswano wokubhida kuzofanele ahlele, okusho ukuthi, kungenzeka abuyisele ikhadi kumphikisi onikeze ikhadi elibiziwe bese efaka amakhadi amane azikhethele wona enqwabeni. Umdlalo bese udlalwa ngokuya ngemithetho ye-tressette. Noma ngubani ophumelela isandla sokugcina uzowina namakhadi entaba, azofaka isandla ekubalweni kwamaphuzu.
Uma umemezela ukuthi "CALL" futhi uwine, uhola amaphuzu amabili, abaphikisi -1. Amaphuzu abanjelwa ukudlala kabili "uSOLO" nokudlala kathathu "SOLISSIMO".
