Lub rooj sib tw ua si yog square, nrog rau caum-plaub me me squares, teem rau hauv ib daim phiaj 8x8. Cov squares me me yog hloov lub teeb thiab tsaus xim (ntsuab thiab buff hauv kev sib tw), hauv cov qauv "checker-board" nto moo. Kev ua si ntawm checkers yog ua si ntawm qhov tsaus ntuj (dub lossis ntsuab) squares. Txhua tus neeg ua si muaj qhov tsaus ntuj nti ntawm nws sab laug thiab lub teeb square ntawm nws sab xis. Ob chav-kaum yog qhov txawv ntawm ob qhov tsaus nti squares nyob ze ntawm txoj cai kaum.

Cov ntawv yog Liab thiab Dawb, thiab hu ua Dub thiab Dawb hauv ntau phau ntawv. Hauv qee qhov kev tshaj tawm niaj hnub no, lawv hu ua Liab thiab Dawb. Cov khoom yuav hauv khw yuav yog lwm yam xim. Cov dub thiab liab tseem hu ua Dub (los yog Liab) thiab Dawb, kom koj nyeem tau phau ntawv. Cov khoom yog cov duab cylindrical, dav dua li lawv siab (saib daim duab). Cov khoom sib tw yog du, thiab tsis muaj cov qauv tsim (crowns lossis concentric voj voog) rau lawv. Cov khoom yog muab tso rau ntawm qhov tsaus nti squares ntawm lub rooj tsavxwm.

Qhov pib txoj hauj lwm yog nrog txhua tus neeg uas ua ntawv muaj kaum ob daim, ntawm kaum ob qhov tsaus nti squares ze rau nws ntug ntawm lub rooj tsavxwm. Daim ntawv ceeb toom tias hauv daim duab kos, cov ntawv feem ntau yog muab tso rau ntawm lub teeb xim squares, kom nyeem tau. Ntawm lub rooj tsavxwm tiag tiag lawv nyob ntawm qhov tsaus nti squares.

Tsiv: Ib daim uas tsis yog huab tais tuaj yeem txav mus rau ib lub square, diagonally, rau pem hauv ntej, raws li hauv daim duab ntawm sab xis. Ib tug vajntxwv tuaj yeem txav ib lub square diagonally, rau pem hauv ntej lossis rov qab. Ib daim (daim los yog huab tais) tsuas yog txav mus rau qhov chaw tsis muaj. Ib qho kev txav mus los kuj muaj xws li ib lossis ntau qhov dhia (kab lus tom ntej).

Dhia: Koj ntes tus neeg sib tw daim (daim los yog huab tais) los ntawm kev dhia hla nws, diagonally, mus rau qhov chaw nyob uas nyob ib sab dhau ntawm nws. Peb lub squares yuav tsum tau nyob rau hauv kab (kab pheeb ces kaum nyob ib sab) raws li nyob rau hauv daim duab ntawm sab laug: koj dhia daim (daim los yog huab tais), tus nrog sib ntaus daim (daim los yog huab tais), khoob square. Tus huab tais tuaj yeem dhia diagonally, pem hauv ntej lossis rov qab. Ib daim uas tsis yog huab tais, tsuas yog dhia diagonally rau pem hauv ntej. Koj tuaj yeem ua tau ntau yam dhia (saib daim duab ntawm sab xis), nrog rau ib daim xwb, los ntawm kev dhia mus rau qhov khoob khoob mus rau qhov khoob khoob. Hauv ntau qhov dhia, lub dhia dhia lossis huab tais tuaj yeem hloov cov lus qhia, dhia ua ntej hauv ib qho kev taw qhia thiab tom qab ntawd mus rau lwm qhov. Koj tsuas tuaj yeem dhia ib thooj nrog ib qho kev dhia dhia, tab sis koj tuaj yeem dhia ntau daim nrog kev txav ntawm ob peb dhia. Koj tshem cov jumped pieces ntawm lub rooj tsavxwm. Koj tsis tuaj yeem dhia koj tus kheej. Koj tsis tuaj yeem dhia tib daim ob zaug, hauv tib qho kev txav. Yog tias koj tuaj yeem dhia tau, koj yuav tsum. Thiab, ntau qhov dhia yuav tsum ua kom tiav; koj tsis tuaj yeem nres ib feem ntawm kev dhia ntau. Yog tias koj muaj kev xaiv ntawm jumps, koj tuaj yeem xaiv ntawm lawv, txawm tias qee qhov ntawm lawv muaj ntau, lossis tsis. Ib daim, txawm nws yog ib tug huab tais los yog tsis, yuav dhia tau ib tug huab tais.
