If I'm not mistaken, they are supposed to be the clay figurines that were discovered in a tomb many years ago. Least that's how it looks to me.

Long solution today:
1.UPs:a8=7,b3=6,f3=9,f5=7,g3=7,d1=7.(Note pairs 46 at a9/c7,and 19 at bc8).
2.When h2=4,h4=9,h7=8,h6=7,h9=2,i9=7,g4=4,e6=9,d6=4,e1=4,i1=6,i2=2 and column i has no 3.
3.Hence h2=2,g2=4,i9=2,h9=7,i6=7.
4.When e4=2,d5=1,e6=9,d8=2,d6=3,f4=4,h6=4,and h4/i5 both can't be More...

A long path:
1)Start at 23,=>UP=27
2)YW:(7=4)g3-(4=2)h2-(2=7)h9,=>g9<>7.UP=29
3)(4)g2=(4)h2-(4=9)h4-(9)i5=(9-6 )c5=(6)c7-(6)d7=(6)d2
=>g2<>6.UP=34
4)(9=1)i5-(1=2)d5-(2)e4=(2-6)a4=(6-5)g4=(5)i4=>i4& More...

1.SSTS to UP=27
2.kraken cell(134)f4 => i4<>9,g4<>4,c5<>2 UP=35
(1)f4-(12)e4d5=(256')agi4
||
(3)f4-d6=(3-2)d8=e8-e4=(256')agi4
||
(4)f4-(4=9)h4-i5=c5
3. (2)a4=a5-(68')ag5=(6)c5 => a4<>6 UP=41
4.(5=4)a3-c1=(4-6)c7=d7-(156=3)cdf2 => c2<>5,c1<>3 UP=81
06/Jan/11 6:55 AM
alternative step 3:
kraken cell(146)e1 => c7<>6 UP=81
(1)e1-def2=c2-(169=4)c578
||
(4)e1-c1=c7
||
(6)e1-e9=d7
