...the possible range for a character's attribute values in T & T is 4 to N where N could be a very large number but isn't likely to be much higher than 20 for a beginning character. (Yes, I know this wreaks havoc with the bell-curve distribution of character attributes - I meant it to do that. Trollworld is full of heroes, freaks and monsters - not a bunch of averages.
buy the rulebook or have a few ganders at the great Tunnels and Trolls blogs out there such as The Delving Dwarf which talks about TnT games, The Lone Delver, where you can read about adventures with TnT solos and The Trollish Delver where Scott Malthouse provides ideas for TnT games and also sells his own great TnT adventures.
Tunnels and Trolls is an RPG with loads of solo adventures - i.e gamebooks that use the game system. The first Tunnels and Trolls solo was Buffalo Castle but there were many more and many more are being created (such as Scott's Depths of the Devilmancer or Tavern by the Sea by Ken St Andre and Andy Holmes).
The greatest treasure in the kingdom lies within the belly of a mad god and you have to retrieve it. Now you have come of age, you must stake your life to brave the tricks and traps of the Fool God’s temple in order to prove your worth.
You can buy Temple of the Fool God from Lulu for the low low price of £2.99.
I hope you enjoy the adventure - please leave feedback. I enjoyed writing a Tunnels and Trolls solo and I will probably write another one.
