Treine seu cérebro como num dojo japonês. Zanki é um treinador de cálculo mental inspirado no Anzan — a arte japonesa de calcular com um ábaco imaginário. Números piscam na tela, um de cada vez, e você calcula tudo mentalmente. Simples de aprender, viciante de dominar. SISTEMA DE FAIXAS KYUU/DAN Progrida por 11 níveis, do 10º Kyuu (somas de 1 dígito) até o 1º Dan (operações mistas de 4 dígitos a 150ms por número). Cada faixa aumenta a velocidade, a quantidade e a complexidade dos números. TREINO FLASH Números aparecem em sequência no ritmo do seu nível. Sem papel, sem calculadora — só a sua mente. Feedback sonoro e tátil a cada rodada. MODO INICIANTE Começando no soroban mental? O Modo iniciante gera apenas operações com movimentos diretos de contas, sem complementos — perfeito para construir a base do ábaco mental. SEQUÊNCIA DIÁRIA Mantenha seu streak treinando todo dia. Acompanhe sua evolução com gráficos de precisão e histórico completo de sessões. TREINO PERSONALIZADO Ajuste dígitos, quantidade de parcelas, velocidade e rodadas para criar o treino perfeito para o seu nível. Treine 5 minutos por dia. Suba de faixa. Surpreenda-se com a velocidade da sua mente.
