How to Play Kereta Kata

Kereta Kata (Word Train) is a game for practising Indonesian syllables. The player is a train driver with Loko, a cheerful red locomotive. Each station shows a picture, and the child couples syllable wagons in order until the word is complete. Once the word is built, the train departs and the next word arrives.

How to play

1. Look at the picture and listen. Loko says the word when the picture appears. Press Space to hear it again.
2. Pick the first syllable wagon. For a picture of a ball (bola), pick BO.
3. Keep going until the word is complete. After BO, pick LA. Each correct wagon couples to the train right away.
4. The train departs! When every wagon is attached, Loko blows the whistle and the train rolls on to the next station.

A station has 5 words. If the child picks a wrong wagon, it closes and Loko says the right syllable as a hint. There is no losing.

Three train lines

Each line has 4 stations. The next line opens once the child earns stars on the previous one. On the Blue and Orange lines, the wagon choices are deliberately similar, for example starting with the same letter, so children must listen carefully.

Stars, Speeding!, and Loko's Garage

• 3 stars for at most 1 mistake at a station, 2 stars for 2–3 mistakes, and 1 star otherwise.
• Three correct answers in a row show Speeding! and Loko's wheels spin faster.
• Stars unlock new colours in Loko's Garage: blue, green, purple, orange, and gold. Pick a favourite for the journey.

Controls

• Touch / mouse: tap a syllable wagon.
• Keyboard: 1–4 choose a wagon, Space hear the word again, Esc or P pause.
• The word voice uses the browser's built-in speech. In Settings you can turn it off or choose Slow voice.

Progress and Loko colours save automatically in the device's browser. Tips for helping children with syllables are in our guide to reading syllables. To start from letters, try Eja Ceria.

Every word on each line

Each station picks its words at random from the line's list, so the order changes every time. All the words are everyday objects children can find at home or school. The game is in Indonesian, which makes it a gentle way for non-native children to meet simple Indonesian words with pictures.

The syllable patterns it trains

• Repeated open syllables such as SU-SU, GI-GI, and YO-YO are the easiest, because the child recognises one syllable twice.
• Two different open syllables such as BO-LA and ME-JA practise blending two sounds into a word.
• Closed syllables (ending in a consonant) such as JE-RUK, BU-LAN, and RU-MAH appear on the Blue Line. Children learn that the final sound is read too.
• Syllables that start with a vowel, such as I-KAN, U-LAR, A-PEL, and EM-BER, often make children hesitate because the first syllable is only one or two letters.
• The NG sound in BU-NGA, PA-YUNG, BIN-TANG, and SE-MANG-KA is one sound in Indonesian, not N then G. It is worth pointing out.
• The AI sound in CA-BAI is read together at the end of the word.
• Words of 3–4 syllables on the Orange Line, such as KA-CA-MA-TA and MA-TA-HA-RI, practise keeping the order to the very end.

Why the wagon choices look alike

On the Green Line, wrong choices come from syllables on the same line. From the Blue Line on, the game prefers choices that share the same first letter as the correct answer, such as BU, BI, and BA. Children can't guess from the first letter alone and have to notice the vowel and the closing letter. If a child often slips here, say the syllable slowly together while pointing at each letter.

Practice ideas away from the screen

• Find objects from the word list around the house, such as a broom (sapu), table (meja), bucket (ember), umbrella (payung), and candle (lilin). Say each name and clap once per syllable.
• Write syllables on paper slips and ask the child to put them in order to make a word, just like the train wagons.
• For words with NG, say them together and ask whether the child hears one sound or two.
