Stop relying on tool tips for your wait.
The riichi button should not surprise you. If it does you need to study your Yaku or pay attention to what is in your hand.
Know what your hand is worth. Stop pushing to win against players clearly in tempai when your hand is worth 1,000. You are risking dealing in to a big hand for no gain. Be aware of the whole game, knowing when you need a big hand to catch up or a quick win to get into or hold the dealer position.
If in the lead go to the fastest win possible or play defensive.
Remember it is extremely hard to deal safe tiles when you locked up half your hand with chi, pon, or kan.
