Use some red fives in place of normal fives as extra dora.
 
* Ari – Use three red fives, one per suit.
* Nashi – Don't use any red fives.

===Kandora===
 
After declaring a kantsu, another dora indicator is flipped in the dead wall. All four players can benefit from this.
 
* Ari – Flip a new kan dora indicator after declaring a kantsu, but I don't know the exact timing rules.
* Sokun. – Sokunori. After declaring any type of kantsu, flip the next dora indicator immediately.
* Late – After declaring ankan (concealed kantsu), flip the next dora indicator immediately. After declaring a minkan (open kantsu per call on a discard or per extension of a minkou), flip the next dora indicator only after declaring tsumo, declaring another kan, or discarding. The new dora indicator is in effect for any type of win.
* Nashi – Don't flip any dora indicators upon declaring kantsu.
 
===Kanuradora===
 
Winning riichi declarers may flip the tile underneath each kan dora indicator and treat that as another dora indicator.
 
===Uradora===
 
Winning riichi declarers may flip the tile underneath the first dora indicator and treat that as another dora indicator.
 
* Ari – Flip the ura dora indicator.
* Nashi – Not used.  Riichi declarers will know in advance how much their hand is worth.
