New game 30 is now available.
Round 1: R T I I E N F B N
I had RITE, INTER, FINITE, and TINNIER.
The other seven here is NIFTIER.
Round 2: I I A F G D I T A
Gah, unhelpful vowels. A final E would have brought FIDGET into play, but without that all I could manage was DIGIT.
Five-letter words look like the limit. The others are TAFIA ("a kind of rum made from the lower grades of molasses, refuse sugar, etc.") and TAIGA ("the coniferous, evergreen forests of sub-arctic lands, covering vast areas of northern North America and Eurasia").
Round 3: Target 227 from 100 5 10 10 9 8
Ergh, the small numbers are almost all pretty large, and even the 5 is not that small. That can make small adjustments rather hard to manage. I floundered for a little here, but at some point considered that 27 was 9*3 and after making that 3 the rest worked out satisfactorily, giving: 227 = 100 + 10*10 + 9*(8 - 5).
Round 4: O A A B D M L E N
I had BALM, LOAMED, and then ABDOMENAL. I was rather pleased with that, and did not even end up writing down ABDOMEN on its own.
Unfortunately for me, there is a spelling shift in the adjective; the correct spelling is ABDOMINAL and my answer is invalid. Since I had been careless enough not to write down ABDOMEN, I would have had to fall all the way back to LOAMED if I had noticed this. But really, I was caught by surprise, and somewhat disappointed that I had not found a full monty after all.
The other sevens are ABDOMEN, ABALONE, ALAMODE (apparently an acceptable form of À LA MODE: "US (of dessert) served with ice-cream"), ADENOMA ("a tumour originating in a gland"), and NAMABLE (acceptable variant form of NAMEABLE).
But there is an eight: DAMNABLE.
Round 5: E E U C R N T W E
I had CURE, CENTRE / RECENT, and TUREEN. I had wanted a final I instead for ENURETIC, but no such luck.
There is a seven here: TWEENER ("a child, especially a girl, between the ages of 8 or 9 and 13 or 14").
Round 6: Target 584 from 50 8 7 4 2 8
I idly looked at what was left after making 50*10, and the resulting 84 has a few useful factors and a solution followed: 584 = (8 + 2)*50 + 7*(8 + 4). Then I considered working down from 600 instead and that felt rather simpler: 584 = (8 + 4)*50 - 2*8.
Round 7: E I A S G S R O H
I had AGES, AEGIS ("protection; sponsorship"), SAGES, GASSIER, GEISHAS, and SIGHERS; I also rejected AIRSHOES without too many qualms. I was a little uncertain about GASSIER and SIGHERS (they both turn out to be valid), so GEISHAS got the nod.
The other sevens are OGREISH and HOSIERS. But there is an eight: ARGOSIES, the plural form of ARGOSY ("a large merchant ship, especially one with a rich cargo").
Round 8: Target 344 from 100 1 9 7 6 10
I was at a bit of a loose end for a moment, then noticed that the target was 350 - 6. That would be particularly useful if the large number were 50 instead of 100, but I wondered if it could be made as 700/2, and that turned out to be the case, yielding 344 = 7*100/(10 + 1 - 9) - 6.
Still within time I experimented with an alternative approach, as the target is 444 - 100. The repeated digit numbers are familiar to me, and I knew that 444 was 37*12, which is also 74*6. That was enough for a different solution of 344 = (7*9 + 10 + 1)*6 - 100.
Round 9: LADIES DIE
I accidentally closed the window with my time in it, but I believe it was in the low 11 second range that I found IDEALISED.
